I am 53 days late for my period, I went to the doctors when I was 12 days late and took a test, and along with the 2 home tests I took, they were all negative. I am bloated, having more discharge, nipple soreness, and aerola darkening. I am Rh negative and am scared that i may be pregnant, but am not showing up on tests. I have had 2 miscarriages already. Please help me
