In My Stomach or In My Mind?

I just had sex on the 5th of July (the condom broke) but for some reason I feel like I’m pregnant. Under my partner’s advice I took the morning after pill and hoped that for his sake it worked. I’ve been sleeping all the time, emotional, having serious acne, headaches and serious urination issues. I wanted to keep the baby and I’m thinking that maybe I’m causing all of this to happen in my mind because it won’t happen in my stomach. I don’t know but I feel really alone and unsure if the morning after pill just didn’t take or if I’m just missing my baby. Please help… 🙁
