So I couldn't remember when my last period was. I ended up taking a 5day early predictor pregnancy test. I took 4 of them all different times I went to the bathroom. They all came up positive. I took them because I felt as if my boobs were hurting, (that's how I felt with my first child.) I'm scared I'm getting my hopes up for nothing though.... What are chances of false positives? When I was pregnant with my first I had to wait 6 days after my missed period for the test to come up positive. I can't even remember if I'm late or not, but I know around this time I should of been getting my period.
