HELP! PLEASE

Guys I am here on an edge to cry 😢 I am feeling this pressure on the right side of my lower stomach. It started on Wednesday and on Thursday I got positive opk. I thought its ovulation pain but it had been 4 days since then!!! It comes at night when I am laying and I cannot fall asleep!!!! I am really really exhausted, and insanely worried about it.

Its not cramp like, its just pressure. Period is due on 11/9

Anyone can give any insight, please?😫

We are trying to conceive.
