1st Trimester

Ovulate late/cycle length long.

So confused.  My cycle length is 34 days and I ovulate on day 19 or 20.  Anyone have this type of cycle?  I got a BFP yesterday at 11dpo and rechecked it again today.....I am pregnant!!!!! Question is, if I calculate how many weeks pregnant by be LMP I am 4 weeks, 4 days.  If I calculate it using ovulation, I am only 3 weeks 4 days.  Three weeks pregnant just sounds weird but that is what I should go with right?  Just doesn't seem accurate to use the LMP, as I would be 5 weeks along on Friday, yet conceived only 2 weeks ago.

Re: Ovulate late/cycle length long.

  • I O'd CD22, a week later then the "normal" CD14, so I go by my O date.  I recommend going by O date IF you know you O'd (confirmed by temping).  If not stick with LMP and wait until your dating u/s to get a more accurate EDD.

    Also, if you know you O'd later, when calling the doctor, if they see you at lets say 6 weeks based on LMP, make the appointment for a week later so you don't freak out if they can't yet see anything or hear the heartbeat yet.  Just my opinion.

  • I O'd on CD32. My OB was going by LMP until an u/s showed otherwise.

    Well, u/s only showed off by 6 days, not 8 and OB won't change due dates unless they are 8 or more days off.

     

  • I'm also a week later O'er, os I was figuring I'd be a week off from the estimate using lmp.  I went for an u/s and the baby was measuring as if I o'd like a normal person.  Go figure - I was certain about our O date, but we're using teh lmp date b/c of the baby's measurements. 

    Like PP said, push your appt a bit just to prevent an uneccesary freak out.  GL to you!

  • I wasn't trying but wasn't preventing when I got PG, so I don't know when ovulated...but I normally have a 32-33 day cycle so I initially went off LMP, which the doctors office did too, since that's all they have to go off of when you call (they will ask about your LMP date). I went in at what I *thought* was 6 weeks, and when they did the sono there was only a sac and that's it. I came back in at 7 weeks 4 days (according to LMP) and baby was measuring 6 weeks 5 days - and they attributed this to my longer cycles.

    As pp stated, push back your date do you don't freak. I didn't know all that before or I would have! GL! And congrats!

  • I also ovulated on CD20 and normally have a 33-day cycle. I would definitely go by your O date, not your LMP, as long as you definitely know what day you O'd.

  • I have a 32-34 day cycle and I o'd on cycle day 18. I'm going by my ovulation date for now until my dating ultrasound. It just makes more sense to me. I wouldn't be surprised if they change my EDD.

     Definitely worth the wait - with my DS my doc had me come in right away (they thought I was 8 weeks even though I told them at the time I had at least a 6 week cycle)... didnt see a damn thing -then had me take a pee test and it came back neg. I was freaking out - sent me for blood work which confirmed I was preg.. but what a frickin nightmare to go through. So, as anxious as I am now to get to the doc - I'm actually in a way glad I have to wait another 3 weeks!

  • My cycles are usually 6 weeks long.  I agree with the others, schedule an appt later and let the doctor know that you have longer cycles.  With my first pregnancy, I went in early (they thought I was 8 weeks, I was really 6), and I had to be sent for a transvaginal ultrasound because my doctor couldn't see anything on the portable ultrasound.

    This time, I was almost 9 weeks at my first visit so the doctor was easily able to find the baby on the ultrasound and give me an accurate due date.

  • You never know...you could be wrong. And just because you ovulate on a certian day, doesn't mean that's when you got pregnant. I doubt an over the counter pregnancy test can detect that you are 3 weeks pregnant. Especially considering even at the moment of conseption you are considered 2 weeks pregnant. Just wait until you get an ultrasound and have them meausre the baby. good luck!

  • my cycles are like that too...usally about 37-44 days apart. i know i got pregnant at the very least 3 weeks after the last cycle cause that's when i saw my husband again.
