Is this normal for being off the pill?

I had to stop taking my pills mid cycle due to the extreme effect it had on my depression. That being said I got my withdrawal bleed 3 days after stopping and ovulated (yesterday) 14 days following the bleeding. However i was and still kinda am experiencing back aches and lower stomach pains.. is this normal? Is my body adjusting to ovulating again? I’m also peeing a ton... which makes me nervous (I know it’s not a uti) And have awful chin acne. Every time I had sex towards the end of the pill and after I used a condom and pull out method.. also checked condoms after.. so I don’t think I could be pregnant. I just want some input and hear personal experiences! Thanks loves.
