help me I don't know what's happening

Estefania
So I've been very nervous these couple of days because my boyfriend and I had unprotected sex and he finished inside on September 28 and 29 BUT the thing is I got the depo shot September 30 so does that affect something with the baby? I've been feeling really weird with my body like my breast have grown and they are always sore also I've been having stomach aches
And I'm always hungry. I can't sleep at nights and I always wake up very hungry. I took a pregnancy test last week but I think it was to early because it said it was negative.
