How accurate are ultrasounds?

kurbie · June 2014

I had an ultrasound on March 4 dating me at 13 weeks exact. I was kinda of shocked because I thought I was 12 weeks (based on LMP). The sonographer said it could be a week off (mind you my blatter wasn't completely full and for the next hour she had me drink alot and kept rushing me in between other patients to try and get measurement and my baby was moving around alot). On April 9 according to my HCG levels I was 17w and 6 days. On April 23 I saw two dates on the screen: 19w1d and 19w5d. The 19w1day coresponds with my LMP and thats what the sonographer told me I am. Also, I'm being seen by 2 doctors and I get different fundal measurements.

Problem: I had sex December 14, 17 and 24. 3 guys. I'm hoping it's the third guy's baby. One doctor says no, but my family doctor says its still a possibility.

I'm pretty sure my period started december 9 or 10 because it always falls every 4 weeks around the same dates as the previous months. To prove I have a 4 week cycle, I went all the way back to June, and as I found, my period fell every 4 weeks. I know they say ovulation is mid cycle but I also know its possible to ovulate early. I asked my doctor and he said its not likely I ovulated on december 17 and that (this was last week) I was in my 24 week not 25th.

So after all this, what are the chances that guy #3 has at being the dad? He's the only one who still talks to me and says if it's his than he will step up and be a dad.

Paternity test will answer that. Is this MUD?

jroll2lo · June 2014

Yup, the only way to be 100% is to get a paternity test. Good luck!

I love how the title leads you to believe one thing, and her question ends up being completely out of left field.

I was thinking the same thing. I felt like I was going to do a math problem.

Sperm can live up to 5 days. Nobody can tell you what you need to know. Instead you'll get a whole lot of comments about your life choices.

I personally will leave your life choices alone but remind you that it's "a lot" not "alot" and "bladder" not "blatter".

I will bite and give a serious answer in case this isn't MUD.

It's possible to ovulate early or late in a cycle so the best way to prove is a paternity test. That being said sperms can also live inside of you for a couple of days. Ultrasounds are pretty accurate to a point. They allow for a 6 day leeway so if baby measures within 6 days of the proposed due date they will keep that due date.

Oh lord OP really? So unprotected sex with 3 different men and only ONE of them you are ok having a kid with? I'm backing out of this cluster fuck of a thread now.....

At the risk of white knighting MUD. I'm feeling a little nice today.

Maybe this is just me, but there were a couple times in my 20's that I made questionable decisions. 2 guys within a week, both were protected but protection can fail. And trust me none of my random hookups were dad material. Smart no, but it happens.

Let's all think about our wild days and the what ifs before we go a little crazy here.

A paternity test is the only way to know OP. Good luck.

Uhm..

MollyHooper · June 2014

Patiently waiting for OP to return.

sandrabrooke · June 2014

I don't think I could land three different men that quickly. But Im a serial monogamist.

Manateearmz · June 2014

Did OP say it was unprotected? Nope. I'm sure we're all making that assumption but she didn't say it. So ease up on the judgey pants.

Anywho I'm sure it's MUD.

I used spermicidal lube in my wild child days. Protection fails sure but if she was sleeping with multiple guys she should have had a back up. Not having one is irresponsible.

Dude, you wear those judgey pants a majority of the time so just because this one touched a sore spot, doesn't mean you need to attempt to police us this much. Can you really expect people not to jump on this one like we have?

Quote box fail.

Whoa, whoa there. My tits are calm. It didn't touch a sore spot. I've never had unprotected sex outside of my husband(s).

My intent was not to police I have the LOLZ at that assumption. I'm just enjoying playing devils advocate today. I'm sure OP will come back and announce that she never wraps it up.

I resent that you think I wear judgey pants. I wear high waisted non-fashionable mom jeans or yoga pants TYVM.

@Nicb13‌ I feel like should get one of those bump badges for this. Think BJ will take this into consideration when I drop the f bomb against the new TOS?
