Cramps on depo

So I got my shot almost two weeks ago now. I got my shot during my period which was the second day. Three of four days later I had sex with no condom but he pulled out. In the week I think we have done it three times or so with no condom. I’ve been getting these little cramps in my vagina like period cramps but they are very slight. Is there a chance I somehow can get pregnant from this?? I’m really hoping not but I just wanted to ask just in case. Thank y’all 💕
