I’ve never really understood when/how to count days past ovulation when you don’t use OPK’s. My fertile window started the 6th, the 10th would have been my highest chance of pregnancy and the 12th was my last day in my fertile window. So what day do I start counting as days past ovulation?

With that being said, how soon can implantation bleeding occur? I just went to the bathroom and when I wiped had small but noticeable light pink discharge. I’ve never had that before so just wondering if it could possibly be that? I know there’s no way to tell until I get a positive pregnancy test but just wondering if I’m in the right time frame for it to possibly be that or if it’s too soon. AF is (hopefully not) due 02/25.
