I'm really paranoid, someone please help

So I'm supposed to be in my luteal phase rn (2 days post ovulation according to my app), but my discharge is still egg whitish and I'm experiencing lower back ache

I have an insane fear of getting pregnant. My last sexual encounter was around my ovulation date, but it was nothing more than fingering. I don't know how, but a lot of my symptoms are pointing towards early pregnancy right now, and I'm going crazy with anxiety.
