spotting

Vivian
Has anyone experienced watery, brown spotting shortly after their predicted ovulation week until the week of their period?
I'm trying to stay positive, but I think I'm out. I had sore nipples for a couple days (which isn't normal) and now some cramping. 
I guess next month I will start using OPKs bc my CDs are lasting 30 instead of 28.. since coming off BC. (which I'm not used to.) 
I know we haven't been trying for long, and it takes a healthy couple 6-12 months to conceive. But, it is emotionally draining. Peace and love ❤️ have a great week.
