10dpo

I’m currently 10dpo, I did my first round of IUI on March 27. I took a cheapie dollar general test this morning which was BFN. Also last night my husband and I had sex and I went to the rr right after and noticed some light pink bleeding. I put on a pad and no bleeding this morning. Just FYI it’s not pertaining to any dryness down there, never have that problem. Just wondering if anyone has experienced this. If AF should arrive, she would be here on Friday but I hope I don’t get it, I want my BFP!
