I don't know the date of my last period, I just know it was sometime in the end of July. So they are not able to tell how far along I am. They did my first ultrasound today, but they were having trouble finding the baby. They said they think that they see the sack, but not sure if they see the heart beating or if it's just my blood flow. They started telling me they think i'm 6 weeks and 2 days about, but they are not for sure. They said it might be a early pregnancy and that's why they are having trouble locating it.. but then they scared me by saying it could be a bad one.. i'm going back for my 3rd ultrasound Wednesday but am so terrified. Has anyone had this happen? Is it because i'm just too early in my pregnancy to see anything on the ultrasound? Please help. I'm so confused and scared, I don't know what to think about what's going on. Thanks.
