Measuring a week behind..

Natasha

I had my appt today. According to my LMP, I should be exactly 7 weeks, however, baby is measuring 6 weeks 2 days. Heartbeat was 111bpm. Dr did a few measurements to make sure we got it correct and believes i might have ovulated later than normal and said Sperm can live up to 5 days.. she also said she felt good about it with the heartbeat being over 100. However I was scheduled to come back in 2 weeks to see how things are going. This is my 2nd pregnancy and I can't help but feel worried even though my Dr reassured me everything Was ok. I had a normal pregnancy with my first but wound up getting preeclampsia at 36 weeks and delivering early. I take a prenatal daily and a baby aspirin (Dr says it can help lower chances of recurring preeclampsia). What do you ladies think? Due date changed from 4/5 to 4/10.
