Weird signs

Makenna

So I got my 3rd depo shot about a month ago! I did have sex around 2 months ago! I’m having some weird pains in my belly and all over the place..my boobs feel a little weird! But I am a little tired.. but the sex only lasted not even 2 mins he promised that he didn’t pre-cum or didn’t cum because I pushed him off of me!? So what’s wrong? Could I be pregnant? Ps: My belly is still SQUISHY. So I would be 2 months soon
