Hello, I have had ovarian cysts for awhile now. On September 6th I had a laporocospy to remove a cyst off my left ovary. My periods have still been abnormal since. October 7, 2016 I had a period, November 10, 2016 I had another, December 6, 2016 was my most recent. I m not exactly sure what dates my fiancé and I had sex this month but it s always unprotected. last night on December 28 we again had sex and later in the night I woke up to cramps. I went to the bathroom and no blood. Today I started what could be an early period but it was very light pink and very light flow. I took a pregnancy test when I got home just to see and it was negative. I ve never had an early period before so I m not sure what is going on. Any advice?
