Help... I don’t want a BFN..😞

My husband and I have been trying for a year now.. multiple doctor visits, taking medications, and finding out I finally ovulated this month. When I took my opk strip test ( on Jan. 3,4) they were positive. I spotted on Jan 6, it has hardly anything it was only when I wiped (TMI sorry). But according to Glow I was suppose to ovulate the 6th and start my period in 3 days. But on my other app it says I ovulated on the 2nd and my period is a day late. For the pass week I’ve had weird pains in my side and some pain behind my belly button. It feels different from my period. I just don’t know what to do, I don’t want to get my hopes up., 😞
