My math isn't adding up...

OK, I am probably just obsessing over this but I am getting a bit worried now? Can anyone tell me if this makes any sense? Warning ? lots of info and might requires some thinking? First day of LMP ? May 18, 2012 Note: Intimacy Dates ? June 9, 10, 11, 17, 20. BBT Spiked and stayed up ? June 12, 2012 First BFP ? June 25, 2012 Blood BFP ? July 6, 2012 First Ultrasound ? July, 18 2012 (Baby is measuring at 6 weeks 1 day- HB 128 BPM) Due date - March 11, 2012 (Based on ultrasound calculations) Based on the due date provided by the ultrasound (going on calculation of baby?s size) the conception date would have been June 20, 2012.   This would be fine, except how could I have gotten a BFP only 5 days after conception when I POAS? Everything says it should take 12-14 days to get a positive urine test?   I guess I am just kind of worried that I conceived earlier and baby isn?t measuring up to par? They did find the heartbeat and said that any heartbeat at 6 weeks is just perfect and everything else seemed normal, but I am worried that the dates just aren?t adding up and the next u/s isn?t until 18-20 weeks, which is still 10-12 weeks away!!! Next apt is in 2 weeks which they will try the Doppler, but I am just a bit confused at this point? Any help is greatly appreciated.

    It isn't an exact science. Late ovulation, delayed implantation, and just differences in growth are all factors. Relax!!

    Same thing happened to me, though my doc's office was only off by maybe 3 or 4 days on the ultrasound measurement due date.  You have to keep in mind just how small the baby is at this point.  One hair of a millimeter off when the ultrasound tech clicks to measure the baby and you've probably accounted for a week of growth right there.  Also, I'm sure everybody's kiddo grows differently - they sure do after they're born, so I'm pretty sure the difference of a millimeter or two before they're born isn't a big deal.  I'm sure you're fine!  As long as you have a strong heartbeat, I wouldn't worry at all.

    This.  Plus you don't conceive the same day you have sex.  It takes time for those little guy to travel up to the egg.  Relax and just go with the good news that your dr gave you!

    Ditto PP's.  All the signs are good, so just relax & enjoy the ride.  All of it isn't exact, from due dates to when the POAS's can pick up the right hormones.  Maybe you peed at a time when the hormone was extra, extra concentrated, so you were able to test earlier than normal.  And you'll never know when you actually "conceived", only "around" when you conceived, because sperm can hang around & then fertilize an egg when it gets there, and likewise, sperm can fertilize an egg just before it would have moved on out.  That window can be days.  So no sweat :)

    Could be a later implantation?

    according to the baby center website conception was the 18th?  Even so, I wouldn't stress over 6 days.  Even ultrasounds are off by +/- 6 days.  try and stay calm.  I know it's easier said than done

    You did measure a bit small based on ovulation date, but as the doctors said you did see a bean and a HB, so for now that's what is important.  You may have had a late implanter, that could accomodate for the difference. 

    If they are going to try a doppler prior to 12 weeks, don't be surprised if they are unable to find it, the baby is still very small at that point, and it's often difficult to find.  Hopefully your OB's office is like mine, and if they are unable to find the HB with doppler will immediately do an u/s to make sure they find it and to ease your mind.  If they don't, I would ask for one.  I hate when Dr.'s offices try too early and then just make you wait it out, that is just wrong.

    Good luck, hope they find it for you at your next appt.
