Can someone help me understand this?

I’m CD21 and I should be 6-8DPO. I took clomid 50mg days 3-7. Last night I had a sharp pinching pain. I just went and used the bathroom, I wiped, and there was an off color string of EWCM. I very very rarely get EWCM, I had it on my fertile week. We haven’t had intercourse the past couple days, so I know it’s not left over semen. My nipples have been HURTING for the past 4 days. Any in-site would be amazing right now. I never had this for my daughter, I did feel the sharp pinch for her and then it completely subsided, but no IB.
