I'm so confused

Amber💙❤💙

So these are my tests for the last couple of days. The lines were the same color yesterday but I've tested 3 times today and they are becoming lighter. We BD 12/31, 1/1, 1/2 and today to be safe bit I'm wondering if I already ovulated. My right side is super crampy today and I'm sleepy. Let me know what you think.
