Af tricks

Has Mother Nature ever played tricks on you? Mine has bee weird for two months now. Last month it started then just stopped tell the next day then was really light and short. Now this month I'm not due tell tomorrow but last night I wiped and there was blood like I was going to start but then stopped yet again. Only this time it was just the one time I wiped. But I still have the horrible cramps. Any advice would be great does my body know I want a baby so it's being mean to me?
