TTC #1 in Fertile Window- Question

Amanda • Mama to Easton 9.18.18 Trying to conceive baby #2 😀☀️
I'm TTC baby #1 I'm 32 and per glow I'm in my fertile window right now. Today glow says it's my peak fertile day. (Fertile week 6th-12) I BD on May 7th and 9th and today I've had super bad ovulation cramps. I tested positive LH surge this AM at 11 but negative past two days. Did I test at the tail end of my surge? Is it possible that my surge was in the middle of the night? Being that today it feels like maybe the egg released. Should I BD tonight or tomorrow night? (The 11th) or maybe just do both nights.. If I caught the tail end of the surge maybe we have a chance of conceiving this month!
