LH peak 3 days in a row?

Ro

I’ve been using my OPK and I’ve had 3 days of peaks now. Very clear test line darker than control line. I had my first AF almost 2 weeks ago after my Mc in late November. Now I’m having brown discharge when I wipe. My husband and I have been BD the last 3 nights since I keep getting peaks on my strips. Is this brown discharge normal 2 weeks after AF started??? I’m currently CD13. So confused!! **before my MC I had 28 day cycles
