I'm a bit confused and not sure if this should be in the PCOS section or here. *TMI* warning below!

I had a chem pg 2 weeks ago. AF was due on the Friday, I did a HPT on Sat and got a positive. Got a slightly stronger positive on the Sunday and within an hour I started spotting and then AF came later that day My period was strange and was bright red but kind of watery, then went to darker brownish blood, then back to more bright red but still a bit watery. In the meantime I had been to the Dr and had a positive blood test on the Tuesday and by the Thursday the HCG results were less than 1. AF went for 6 days, so finished last Saturday/Sunday. This week though I have had some light pink spotting on a few days and then this morning some bright red spotting. I am due to ovulate this weekend, I have had some almost EWCM in the past day or two but the OPK tests have been very negative. I have had cramping on both sides which feels more like AF pains than O pains.

I'm not really sure what I'm asking here but do you think the spotting is from the mc or maybe just due to my PCOS? I can't get in to see my Dr until next week but even then I'm not sure if it's worth paying $40 for him to tell me it's "normal" or whatever and send me away. It's all too confusing for me and my body seems to be up **** creek!
