Could Abdominal Cramping Along With Sore Breasts Be Pregnancy Symptoms?

Hi i was wondering if i could be pregnant i had sex two months ago, last month i got my period for 4 days the first two days there was only a small bit of bleeding and it was lighter than usually, it looked pinkish/orange color it was weird then for the next two days it was really heavy. For the past week i have been feeling really weird, my period should come in 10 days and now im geting cramping for the past three days, my beasts are sore, i get back pain and my belly is really big, i was wondering if this could be pregnancy or can this be just because i will get my period soon.
