My last cycle was March 25, 2015. I had sexual intercourse on April 3,8, and 12 unprotectedly. On April 10th, I had light spotting that was pink with a little brown. I began having pregnancy like symptoms the week of April 20th. I encountered sore breasts (so tender that I couldn't stand to touch it or for water to touch them;felt the pain under my arm), very nauseated (never vomited), I slept more than normal, everything I ate had to have either salt or sugar in it, I was very irrititable, and I was just tired all of the time. These symptoms lasted for 3-4 weeks almost. I took a toal of 7 tests and they all were negative then I finally got what I thought was my cycle of May 9, 2015. It was very light and short. I couldn't fill a thick pad, barely filled a thin one. I literally walked around wearing a panty liner for 2 almost 3 days; I normally have a 5 day cycle. I have yet to have a cycle for June but I have no symptoms. I feel normal but I'm always sleeping and I'm now hotter than usual and have to sleep with a fan. Could I be pregnant? What should I do?
