Hi Ive Gotten My Depo Shot While On My Period

Hi ive gotten my depo shot while on my period which was monday on the 23rd of april and waited exactly a week to have sex which was april 30th. he ejaculated in me it kind of burned once i peed it out. I took a plan b on the third day just to make sure i wasnt pregnant. I had sex on may 7th & had sex today may 8th & once i peed & wiped i fould light pink blood on the tissue, i wiped like 3 times & it went away. Recieving a lot of cramps. ButIm not recieving spottings or anything & kinda nervous on what it means whether im pregnant or not?
