I had my period late. It is going on three weeks so I decided to go to doctors about it yesterday. I was given a urine pregnancy test which came back with a faint two lines of positive for pregnant. Then had bloods done.I won't get results back til Friday and a scan done which showed no sign of pregnancy in my uterus. Will I be fine to go through with my BA I have scheduled for Monday? I have my doctors appointment on Friday afternoon where she will give me her advice but I'm really worried.
