On the first day of my period, i’ve been experiencing severe cramps, the left side of my body goes numb, I have a cold sweat and shallow heartbeat. I immediately have to run to the bathroom to go number two. It’s not my normal number 2. Very foul smelling and different consistency. This painful episode where I feel like I’m dying typically lasts about 20 minutes and then goes away. What the heck is wrong with me?
