Could these be pregnancy signs oris it just me?

Hi, i ovulated over a week ago, me and my partner had sex nearly everyday leading up to ovulation, everyday during ovulation and then after.Now i have been experiencing abdominal cramps, lower backache, my breasts seem more full and i am having mood swings worse than ever before. However i am due my period in a week so dont know wether this is jst pms symptoms or early pregnancy symptoms.Can you still get pms symptoms a week after conception or is it just my mind playing tricks on me as im hoping to be pregnant? this 2 week wait is torture! x
