Pregnant (maybe)

So June 1st I got my depo shot but my doctor told me to use condoms this whole month because it wouldn’t kick in and work till next month (September 1st) and my boyfriend and I had sex 2 weeks ago unprotected the 5th, 6th, and the 7th. and he pulled out, and my fertile window was in like the next day after it. I heard pre cum gets a lot of girls.😂 but these past couple of days... like my nipples are darker than usual and I have been feeling nauseous to certain smells... like my boyfriend was eating popcorn... I love popcorn to death but I just wanted to throw up. I have also been getting cramps in the lower part of my abdomen. I’m getting a pregnancy test in the morning so I can know for sure ! But I’m not saying, can you guys diagnose me and tell me if I am? I just wanna know what y’all think. I literally can’t sleep.
