CD10, blood streaks in CM. HELP!

Hi ladies,

Apologies if this is TMI.

I'm CD 10, AF ended 5 days ago. My husband and I BD'd CD6 and last night (CD 9). After sex last night and this morning I noticed blood streaks in my CM/the semen. When I wiped again there was nothing. I've never noticed this before and am concerned.

Were we just too rough and that's what's causing the blood? It didn't seem rough, passionate...But not rough.

My opk test this morning and last night was negative. I think I'm approaching ovulation but not there yet. Anyone experience this before? Any idea what's going on? Should I be scared?
