I haven’t been on birth control for over a month and I have been having unprotected sex with my long term partner. I have pelvic pain during sex and cramps and back pain for the last few weeks. I have missed my period by 4 days now and I took a test but it turned out negative. But I have been nauseous and tired as well. What should I do? Should I take another test soon? Should I call my doctor? I may have an ovarian cyst or something because I also have signs of endometriosis for YEARS! I just wanted some second opinions.
