Hi I'm very normal with my periods I have a cycle of 28 days my last period was on 12/25/10 and I had sex with my husband I don't know what days I was suppost to get it on 1/22/11 but it never came when I was a week late I took a pregnancy test it was negative now when I was 15 days late I started to bleed but only when I wipe with tilet paper and not all the time only sometimes today will be my third day like that and my doctors appoinmnet will be intill next Friday and I don't know what's wrong this never happened to me

It may be an off cycle, or you may indeed be pregnant and the previous test just didn't pick it up yet. You can try another home pregnancy test, or wait and see the doctor on Friday where they will do a pregnancy test in the office.
