My last menstrual cycle began July 24th. I had unprotected sex July 5, 6, 7, 8. Saturday August 17th my hcg quantitative serum was 1. I had severe pain, fainting, and moderate fluid in my abdomen. They said likely an ovarian cost ruptured. They said I am not pregnant. I am now 3 days late for my menstrual cycle and my hcg today was "less than 2." I feel nauseous, tired, moody, and bloated. I generally do not feel well. My bloodwork was normal they said. Any idea what's wrong?
