Ashlea
I had a tiny bit of spotting so I went to the doctors Friday and got another blood test done to see if my hcg levels are rising which they are my doctor sent me for a scan yesterday (Monday) their was nothing their they said it was because its still very early I'm roughly 5 weeks pregnant! Still getting a very strong positive reading on a pregnancy test! Just wondering if any one else has went for a scan this early and seen nothing. The lady informed me that it's normal and could possibly be due to only being so early. And got told to go back in 2 weeks time..
