PLEASE HELP!

I’ve posted so many times and haven’t gotten an answer, anything helps please! So i got off the depo shot in January, i had light spotting the beginning of this month! Ik it’ll take time for my period & fertility to get back to normal! Now i had sex on Sunday, he pulled out and came on his stomach, no chance of cum even getting in me. I guess my question is; if you were on depo, what’s a rough estimate of when your period came back? Ik it’s different for everybody, and i’ve googled and ask my doctor, she said me getting pregnant rn is very unlikely but idk i guess i’m nervous as to when my body will be back to normal!
