My last period was from July 2nd to the 8th and it was lighter than normal. But I had mid cycle bleeding between June and July. My period was lighter than my mid cycle bleeding, and I'm on birth control, have been for almost 4 months. Recently I've been having severe nausea, and massive migraines, my boobs are a little tender. I took a test after my last period ended because my obgyn suggested it but it came out negative. I'm not supposed to get my next period until the 3rd. What is your advice for me?
