A few months ago, my husband and I had unprotected sex. I got my period 2 weeks late but the length of my menstrual cycles vary from month to month. This period was the normal 7 days period (not spotting). After that period, my vagina was dryer than normal and my next period came 3 days early and was very "normal" yet again. After this period I thought I ovulated due to my CM changes (went from dry to egg white to kinda dry) and I have been experiencing nausea and bloating which are typical during ovulation and PMS but are coming at odd times and my breasts seem to hurt a bit at weird times. Its not like when i am going to start my period (my nipples become extremely sensitive and tender). Instead its like random sharp pains in one breast at a time but it goes away quickly. I took 2 pregnancy tests 2 weeks after 1st period and another 2 weeks after that. I am just wondering if I could be pregnant since I have heard all this talk of women becoming pregnant and having neg tests and bleeding.
