Hi, I had some pelvic pain and it seems to be doing better. I am about 11dpo and have been having bad headaches along with the pelvic and backaches. I wound up having a 2 day heavy period which abruptly stopped. I've never experiences headaches during period and even after the 2 day. Perio my head is still pounding. I'm getting BFN on tests also!  I went to hospital and they checked for ovarian cysts which they did not find so I'm completely lost.
