Could i be pregnant?

Rae
I have been feeling some throbbing almost like a heartbeat in my lower abdominals, not constipated, boobs are somewhat swollen and sore but no color change of nipples. Also im not sure if its bloating or what but its a bit bulgy around my pelvic region. Im done ovulating and my period is due in a little over a week. Any ideas to what this may be?
