So I went for my first ultrasound this week thinking I was 6w3d. Baby measured 5w5d and doctor wasn't worried but wants me to come back next week for a followup ultrasound and said by then, we should definitely see a hb. My concern is that my dates were so far off. With my DD, my dates were 2 days off and with my angel baby my dates were only one day off. I had a d&c may 8, based on OPKs I ovulated may 24 or 25, and got a BFP June 9 after a negative June 6. We DTD may 22 and may 24 only since our mc so I know when I got pregnant. So, if I implanted a little later, would that cause the baby to measure behind or should baby be measuring based on fertilization? I am going to ask my doctor next week, but just wanted to know if you ladies had a similar experience good or bad and if you know if dating is from fertilization or implantation. I should also mention, doctor saw a yolk sac and fetal pole and what he thought was a heartbeat but with the size, he couldn't get a good view to measure the potential hb.
Re: Should I be worried?
Yes, it is. My first baby was the same way - she is two now. She measured a week behind early on, and no heartbeat was heard at the first scan, they told me it was a blighted ovum and to expect to start bleeding soon - I never did.
My miscarriage had dates that were way closer in line than that.
This pregnancy is about 5 days behind, but has picked up the pace quickly and would now have me delivering 2 days ahead of schedule. Sorry for the rambling but I'm an engineer and I always find numbers and data help me when I'm feeling anxious. I know it's hard to wait but you sound like me, and it usually makes up time a few weeks later!
Sending good vibes...
