Hello all

i am new to this but I need advice because I am finding that doctors are not helping right now. Ok I have never had a regualr cycle so when I was 14 I went on the pill and stayed on it until last august. I was 21. Now it has been almost a year and I had a period last october and on june 3rd. Since june 3rd I spot a lot and has gone to my doctors often. Now my bf of 7 years and I want to try but not try to have a baby. Sounds odd but we just dont use birth control, and we havnt since december. I was thinking about taking my temps. I went to my doctor and he put me on progesterone pills to take for a week a month then I get a period every month, but when I took it in may I had a period for 3 weeks almost until june 3rd. He wants to put me back on birthcontrol, but I dont wanna. So I got a second opinion and she sent me for an ultrasound and it came back normal, and I had a pap test and that came back normal. My bf and I have sex regularly, but for the past 3-4 days I have had this weird spotting first it was a bright red, but watery looking, then it turned brown with clots. But it only occurred when I went to the bathroom. And I have had cm but not a great amount. Sorry to be graphic but since I dont know when I ovulate or if I even do and I have some pregnancy signs at the moment. Has anyone gone through this or has any advice of what to do next. This is all new to me and so many woman I know have had trouble conceiving and I would rather not have to go through what they have to get pregnant.
I am just so frustrated cuz all the doctors are not giving answers or options.
Thank you.
