Spotting at CD12 and Ultrasound Results

So this morning I went to do my ClearBlue OPK, and when I wiped I saw brown bloody discharge on the toilet paper. I was shocked. I automatically went back to remembering when this used to happen to me all the time before I ever went on any hormonal birth control. Bleeding in between my cycles every month was the norm for me years ago, but I always attributed it to my diagnosis of PCOS. 

Speaking of diagnosis, according to my ultrasound that I had last week, no cysts were visible on my ovaries and they are measuring normal in size. So my doctor is officially not diagnosing me with PCOS. But she does want me to redo my scans and bloods again in 3 months if I'm not pregnant by then.

Anyway, the ClearBlue OPK is negative, but I did a Premom brand strip and its coming back more strongly than it was yesterday. Went up from 3.5 to 7.5. So now I'm just really confused about what it is happening. I'm bleeding, and when I wipe you would think I was menstruating, yet it's not flowing enough to be a period. And then my OPK strips are still rising? I happen to speak to my doctor today because she called me with my results, and I brought this up to her, but she doesn't think that it's completely abnormal. She says that this might be a positive sign of ovulation coming. But like, who wants to have baby making sex when they are bleeding? That sounds super counterproductive and a huge turn off. 

I hope this stops tomorrow and I still get my positive OPK... Right now I'm just discouraged and confused.
