Ally, I had that too last night, ewcm streaked with bright red blood, just before we BD'd. I only noticed because I was putting in preseed before BDing and there it was on the applicator. I have never had any red blood before O. It's weird. Not sure if I scratched my cervix checking cp and cm or what. I'm pretty sure I haven't O'd yet, maybe in the next day or two, so I don't think it's ovulation bleeding.
Right all my bloods came back normal so no explanation why I still haven't had period in 78 days!!!
