pregnant or not

So I was put on the depo shot on the 14 of may and I had sex on the 19 and the condom didn't really do its job if you know what I mean yea it broke and he ended up getting a little bit of you know what inside but we think it's okay because I was on the depo but now I'm getting some really weird signs and it's the 26 of may now and I've been a little over tired and I have going to the bathroom a lot #1 but very much of #2 and I'm having these pains in my stomach but I've been reading a lot and most of them are in the lower pelvic area but mine are more in my upper stomach I mean yes I've been getting some cramps like I'm gunna start my period which I am coming up on a day late if anyone could just give me a hint of what you think might be going on it will be greatly appreciated
