Missed Period

Maritza

Hi ladies-

I've been TTC for a. While now. I just have a question. I am 10 days late and I had unprotected sex. After we were done (sorry for TMI) I bled but for a day or less. So I thought I started my period. I then had unprotected sex again, but didn't bleed afterwards. Have any of you guys experience that and been pregnant or have a explanation? Please help ladies :) thanks
