Weird cramping the day after suspected ovulation?

So DH and I have decided to try a more traditional approach to baby making this cycle. No temping, no OPKs. Just listening to my body because the constant tracking was driving me crazy. We’ve been BDing the last week every other day, just in case. I am CD 17 right now.

So, I had what I think was ovulation pain on the right side all day yesterday. It wasn’t uncomfortable, just noticeable. It was our day to BD, so we did. It was the first time in a few cycles where I thought I could feel ovulation.

I woke up at 5 am with some really bizarre cramping around my belly button. This is something I’ve never experienced before with any of my cycles. Does anyone know what this could possibly be? Am I thinking too much about it, am I just gassy haha? I don’t really feel gassy.

Any insight would be awesome!
