I was suppose to start my period Friday and I didn’t. So Saturday I took a $1 pregnancy test and it was positive. Sunday, around 6 I started bleeding bright red blood. Went to the doctor and they said my HGC level was low. The lowest was 6 and I had 11. They said I could be too early to test or could’ve just not been pregnant. But I was wondering what could cause a positive pregnancy test?
