My first pregnancy my baby was measuring 6 weeks when it should have been measuring 8 weeks, a week later there was no heartbeat. We were sure if the dates then as I had IUI treatment. I now have a 4 month old baby I just found out I am pregi 6 weeks + 4 days naturally so really excited! My first period after I had my baby was on the 3rd of August so going by that date I should be about 8 weeks or so pregi but on my scan I measured 6 weeks. We made love twice on the 12th August & 20th August, I guess I could have ovulated late but now I am worried, won't get another scan from OB till at least 2 weeks and so nervous as I have no symptoms!!! But I guess my body still didn't fully recover from first pregnancy and now I'm pregi again.
