Q: Baby measuring 2 days behind ovulation?

I am pretty sure of when I ovulated before getting my BFP. I ended up starting a yeast infection right around ovulation so I didn't track my CM as much. My first ultrasound put my due date back two days. That means I would have had to conceive two days after my latest possible ovulation date (wasn't temping just doing opks). I am really nervous. The heart rate was 146 and doctor said it is fine because the baby measured within 5 days of my dates. I have had two missed miscarriages so I guess I am just worried baby will slow down on growth until it stops. Although last time baby was measuring 8 days behind with a weak heartbeat and then stopped growing a week later...anyone else measure behind even though they were sure of their dates?

Good evening everyone,
Congratulations! I am totally sure that you all know that none of the tests, or anything man made if 100% foolproof in front of a natural process as pregnancy! Being pregnant is a blessing within itself, which no manmade thing can recreate. So i would suggest you to not comoletely rely on these results always. I don't say they are wrong, but they are not comoletely accurate, as well for it is us who have set the rulers, and levels for them. think the measurements can be off. My baby measure 7wks 2 days and 7wks 3 days on the ultrasound pics she gave me. She didn't change my due date though. Due dates aren't exact anyway so since I'm around that date, she said it's fine.

With my son, I knew the exact day that I ovulated and at the 6 week ultrasound he measured a few days earlier. I had had two miscarriages as well, so of course it worried me but I just needed to be reminded that babies come in all shapes and sizes. Your babies heart rate is excellent and 2 days is nothing to be concerned about. I completely understand though!

My daughter measured 4 days behind my O date, at my 8wk dating scan, and my OB was fine with it. She was ahead of O by the 12wk scan. They can be off a bit on measurements, esp early on. Babies grow at lightly diff rates as well. My current pregnancy measures 6 days ahead of my O, on all his scans. That's means I conceived 3 days before I even had sex (hubs wasn't even in the province at the time). Nothing is exact, don't let it stress u out!
Congrats! =))

Interesting! It seems like early ultrasounds are not 100% accurate by any means. I am thinking maybe my babies just measure small on ultrasound. My son was only 6 lbs 6 oz

I was temping, so I feel like I know my ov date. Baby measured 4-7 days bigger/older. I had two appointments, one at 6 weeks and one at 8 and they said that the measurement was really only good to about a week. Last pregnancy was an IUI baby so we knew the exact date of conception and he measured about a week bigger too. They don't turn out particularly big, 7lbs, but just tend to measure big on the early US.

My son was measuring a little behind too now that I remember it. My doctor moved my due date out 3 days and then was surprised when he came "early" but didn't surprise me because I always thought the doc had my due date wrong. I don't think I would be so nervous now about it if it weren't for my fear of miscarriage. Although my recent miscarriage the baby was growing veryyyy slow and had only a "flicker" of a heartbeat so we were pessimistic about that anyway

Thanks. I didn't temp so I have no idea exactly when the egg would have dropped. And the doctor said the ultrasound tech can measure a little off sometimes. I just get nervous having had two miscarriages. Hopefully I will feel better as the pregnancy progresses

I wouldn't worry about 2 days. Opks detect a surge. It can't tell you the exact moment the egg was released. I know when i get ovulation cramps they last at least 12hrs so does that mean the egg was released at the beginning of my cramps or at the end or even hours aftee the cramps end? I get a strong positive opk the day of or the day before ov cramps. I understand the fear after having miscarriage though. Try not to worry unless the doctor says something is wrong. My first two babies heart rate was 150 so close to yours and they are both happy and healthy, born full term.
