My period is due in 7 days, I have been a little grumpy lately, i make more frequent trips to the restroom and I ALWAYS feel hungry. I feel fine while eating but the second I stop (no matter how much I eat) I still feel hungry! I've been having cramps for 4-5 days. Somethin is telling me I'm pregnant but that other part of me is telling me I'm overreacting?? Help please?
