I hope I’m not pregnant

I recently just got out of a relationship and I was on and off my birth control I know in my heart I’m not pregnant I just feel like in my mind it play tricks on me so much because I start over thinking.

Help what’s a good way ladies to keep my mind off of pregnancy

P.S I’m only a day late and I know it’s mostly stress and not being on BC anymore so my body is getting used not having the hormones
