AF due

Af is due this friday on the 8th. But last week for like 3 days I had some cramping and today my nipples are a little sore. Now i never have cramped a week before Af is Due also my nipples never get sore. Not even with my last pregnancy did my nipples get sore. I talked to my mom and she knows i want to have another baby so bad because my husband and I have our son together who will be 5 this month. But she seems to think it might be A) in my head or B) its not cramping in my uterus its my bladder. I just really need some prayers and if your not religious maybe some good thoughts. We have been trying for 4 years but a year into trying ( Aug. 2015) i stopped having periods until Aug. 2018 they started back up again. And now i can really track them but no such luck to getting pregnant.
