In 2008 I had my tubes tied, I have 2 children... I have sex on a regular basis with my boyfriend and don't use any form of contraceptive. I finished my period 4 days ago. It lasted 3 days and was fairly light no cramping which is odd. I am now experiencing cramping, nausea, hot flashes and a constant need to eat. And can't seem to get enough sleep. What could be wrong? I have tried taking asprin for cramping, and resting due to being so tired but nothing seems to help. I have my ac on non stop due to constant hot flashes and I'm eating like no other. As far as nausea I tried lemon ginger tea and crackers. Nothing helps please help me
