To women who were actively TTC

bheatz22 · July 2015

Hey ladies! I'm going to see my doctor tomorrow for all my blood tests and stuff and I'm very excited. I do have a question. Based on my LMP I should be at 6 weeks today but I had a very wonky cycle last month and since I was charting I know I ovulated on July 4th. This means I'm only 4 week and 3 days. Will my doctor go by the LMP or my ovulation? I'm concerned because I don't want the doctor to think I should be further along than I really am and get concerned. How have other women who were actively trying dealt with this situation? Do I just bring it up or will they still go by my LMP?

Any advice would be helpful. Thank you ladies!

I would bring it up. My doctors office uses an early ultrasound to check the due date. They go based on your LMP unless the ultrasound is more than a couple of days different then the LMP date, then they use the ultrasound date. I hope that makes sense, I'm confusing myself!

bheatz22 · July 2015

@kh1824 no it totally made sense. Thanks! I'll bring it up. I just know they already have me down as EDD 3/15 when I'm pretty sure it's 3/26.

I told my OB. They understand charting, it will make sense to them!

Hi there! I'm about 2 days behind you!

This is one of my pet peeves. A lot of these OB's, my old one included, use this corny looking wheel chart and they go by the old "40 weeks since period". It's like they don't trust women to know their bodies.

I understand your concern. I mean if they're going by their date they could try to induce you before baby is ready. Hopefully, they'll do an ultrasound and see that your date is spot on.

@CCLow87 that's good. I know some OB's don't like charting so I wasn't sure if anyone encountered resistance.

@Kristin83 That's my fear. When I got my pregnancy confirmed at the hospital (just urine and it was a formality to see my OBGYN) they wouldn't listen to me when I said I think I'm only 4 weeks. I don't want to be incuced before my little pumpkin is ready.

Good Luck! I am in the same boat I didn't ovulate until cd20 so I plan to tell them so. I think I may bring a copy of my chart JIC.

There's a MAJOR difference in growth for that span of time. If your OB/midwife doesn't listen to you at first, dating ultrasounds with fetal size will tell them a lot. This is also why they ask for cycle length a lot of times, because the average luteal phase is 11-14 days.

@kosmo86 I didn't ovulate until day 26! That's crazy because I usually ovulate between day 14-17. That's a good idea about the chart. I have min on my phone so hopefully it will help my OBGYN

@skruhmin That was why I was so worried. I know there's a huge difference between 4 weeks and 6 weeks.

Thanks ladies your responses have all been super helpful!

My nurse asked me about my chart in our initial consult at least. Maybe not all OB's understand the concept. (if they dont, they should!)

I HATE THE STUPID WHEEL! Umm.. at least make it look like you're putting effort into dating my pregnancy. lol

J234 · July 2015

I showed my ob my app, the chart I made for her in case the app wasn't working and she busted out the wheel. They did the dating scan to measure and it was only a three day difference in the end. I thought it would be a bigger difference, but kiddos grow at different speeds.

I wasn't actively TTC but I told my OB I wasn't sure if the little bit of bleeding I had in June was actually my period but that I felt different within the next couple of weeks and then I took a pregnancy test they listened and gave me an ultrasound that made sure that my June semi period was a period. I love my OB they really listen and take their time with you. Bring it up to your OB I'm sure they'll want to know that you were charting.

I was using opks only and told them I believed I ovulated day 20. They said we'll see what the sonogram says...and when my ultrasound matched my date exactly they went with it no problem.

Jellybeanqueen13 · July 2015

My doctor goes off of LMP even though I charted BBT and did OPKs and know my exact ovulation date. I would bring it up, but don't be surprised if they still want to go off of your LMP... mine did.

jupiterthecat · July 2015

So far my doctor's going with my O-date EDD, but I took an Ovidrel trigger, so I know for sure when I ovulated, and he prescribed it, so he knows too (I'm still seeing my RE-- we'll see what happens when I go back to my OBGYN... I'm a little worried they'll make me change to LMP, which would be dumb).

I know in the past my OBGYN has said they go by LMP unless the dating ultrasound is 5 days off from that... sounds like yours will be for sure. I don't know why they don't just consistently go with the U/S dating. I understand why they don't go by charting... I'm sure there's a lot of error in charting, although TTCers put a ton of faith in it. But I just did a Google scholar search and found articles specifically documenting greater accuracy of using ultrasound dating, I'm sure because of the variation in ovulation timing (and I guess also implantation timing). Why wouldn't they just go with that?

@bheatz22 have you considered just giving them a different LMP date? 14 days before you ovulated if you know for sure when you did. It's not really "honest" but it eliminates confusion.

meg_2006 · July 2015

I would just explain it to them. Doesn't matter much anyway, they usually change it with the first US.

bheatz22 · July 2015

@didi0308 I legitimately never considered that. Now I feel silly :P

Seriously ladies, thank you all for all your help! I feel better about going tomorrow.

This is what I did.

bagel37 · July 2015

Like what a lot of people said, bring it up with your doctor and most likely they will date off your first ultrasound. Last time my lmp put me off by a week, so they moved my dd. this time, I'm going off my ovulation date which puts me in March.... Even though my lmp would put me in February. I guess we will see next week when I have my first ultrasound!

With my previous three kids, I knew the exact date of conception, and so I gave that info rather than my LMP (which with #2 and #3 had been since before I got pregnant with #1 - I got pregnant postpartum without AF ever returning). Cool tidbit - I also knew which ovary i ovulated from bc of mittleschmertz pains (sp?), and it was confirmed at the first ultrasound; neato!

I too get the pain. I think this one was a righty. Can't remember with my boys.

bheatz22 · July 2015

Thanks for all your help ladies. I told my doctor about my LMP vs ovulation date. She decided to schedule my ultrasound in two weeks to confirm the age of the baby. I'm excited but sad because my DH can't come

(

@oceanchild I'm pretty sure the baby on is the left because I get mittleschmertz pains every cycle too.
