When it comes to my period I'm always on time but last month I missed my period. I was sexually active on one of my fertile days and then ovulated two days later. A week later I started bleeding but it was only for two days I bought a pregnancy test and it was negative and then I took a blood test and that was negative. If I'm not pregnant then why am I feeling the pregnancy symptoms. I still haven't started my period which is now 34 days late.
