I have been experiencing slight, to more oppressive nausea for about a week. Also, headaches and fatigue and a feeling of fullness after eating less than usual and sometimes no hunger at all. Aversions to some foods, none in particular. I have also had more incidents of burping and urination and bowel movements. The kicker is, I haven't had sex for almost 2 months now and have had two heavy periods since then. I have taken several pregnancy tests all with a negative result. I was on BCP for 10 years and stopped taking them for about 4 months. I started taking them again about A week and a half ago. I am wondering if this could be the cause of my symptoms? I never had this sick feeling reaction when i first starting taking them 10 years ago and it seems like a long time for nausea to be present as a reaction. I know that there are very rare occurrences when women experience heavier bleeding during a pregnancy or have not registered a BFP on a home test for as long as 6 months into a pregnancy. Also, there have been cases where women do not begin experiencing morning sickness until about 4-8 weeks into a pregnancy. Does this sound like I could possibly be pregnant or something I should seek professional medical evaluation for?
