Well my progesterone that was taken monday came back at 1.3 so looks like my spotting is my period, or thats what the doctor said. If my lining is really thin tomorrow at the scan then it will be confirmed as my period, if it's not then I guess the spotting will turn into a bleed at some point. I guess it's not likely that I'm going to ovulate in the next few days (i.e. I just ovulated later then what I thought) cause a level of 1.3 is what you would have on or just after menses. So now that I know what I know I'm hoping my scan tomorrow shows a thin lining, thus classifying cd1 as march 13, the day of the heaviest pinkest spotting, if the fistula is behaving then we'll go ahead with an FET this cycle and if it's not then I think I'll go on bcp for one month to regulate my cycle and bring on my next cycle when I finish the pack of pills. Thats where I am right now, so a lot is hinging on the scan tomorrow.
