Twinges in Ovary

Soooo me and my husband have been TTC for like the past 6 months. My cycles are weird. Sometimes they’ll be every 32 days.. sometimes 35, 42. But on adverage they’re 40 days. Anyways, I’m literally supposed to ovulate today (based on 40 days)... but one week ago, I had what looked like egg white cm.. and it had a little blood in it. Not much. Just some. Soooo idk what that was. Today I am suffering from a headache, and the last three days I’ve been having twinges in my right ovary. Sooo I’m not sure what’s going on with me. Lol.
