So confused

I've already had my period for the month of May, BUT I baby danced on the day I was suppose to be most fertile on in April.... It looked like a normal period, my breast were so tender that I couldn't stand my husband or my dogs to lay on me scared they touch them. Then I had my 'period' and ever since my left breast near my armpit is sore-like, I've had cramps just about every day, I've only experienced some CERVICAL MUCUS. I had a woman at work come up to me and say that I've gained a little bit of weight, and I'm very tiny and never gain weight so this is a shock for me, so I proceed to tell her that I think I'm pregnant and she talked about her daughter heard a cry in the middle of the night outside but they don't live around anyone... Crazy, I know. My husbands grandmother told me someone is going to get pregnant here soon bc she's craving everything.. Did anyone ever have this problem and had a 'period'? Or can help me out with this.. My period isn't until June 3. And remember I had what seemed like pregnant symptoms before my last period.
