Thoughts?

This is the third month TTC. On The 17th I thought I felt ovulation from my left ovary. I thought that’s cool because I BD’d the night before. I didn’t believe it was ovulation though because that was CD13 and I always feel ovulation on CD20 or 21. BD’d the 19th and 22nd. On the 24th I started to feel like I was ovulating out of my right ovary so we BD’d again. Ever since I have been in so much pain. It is now 3dpo and my lower stomach feels heavy and has been in a dull ache. I know it’s nothing baby related (unless I really did ovulate on the 17th) but I don’t know what it could be. Any ideas what could be going on?
