I just had my first sonogram today. I'm 8 weeks, 3 days and due April 22nd. The tech found what seemed like 2 sacs, one had a baby and the other didn't. Then the doctor told me it was possibly a twin but there isn't anything showing up. They will recheck it in 4 more weeks with my next sonogram. So there's the possibility that there was twins (no twins on my side or boyfriends). I'm glad I didn't know this before and didn't have my mind set on twins. It would have been a blessing, but I'm okay. Any input?
