Ovulation pain? Worried!

Hi guys so basically on Monday I was having ovulation pain (very sensitive to it) and just to be sure I tried an ovulation strip which came out positive and comfirmed why I was having the pain. At the moment me and my husband are ttc (2nd month) and so we were intimate for 3 consecutive days.

On Wednesday I got the dull pain again (which never happened before - always get it for ome day only) and tried another ovulation test strip just in case but came out negative, the same happened yesterday and today also with always negative results.

Now I’m getting worried that something is wrong cause this never happened before - the pain is not sharp and doesn’t bother me but now that I know it’s there I am very worried... did this ever happen to anyone before? Any feedback? Thanksxxx
