I think I missed ovulation 😭

I had lots of EWCM a few days ago and cramps which typically indicates O for me. I don’t use OPK’s. Don’t ask me why I don’t, I just haven’t bought any yet. But now I’m technically 4dpo and getting very water cm and bad cramps near my right ovary and lower backache. My cycles are kinda irregular and I thought I caught O perfectly this month before my husband left town for a few days. But now I think I’m actually ovulating and the last time we BD’d was the 16th. So I’m pretty sure I’m missing it. 😭
