Stomach cramping during running

B💑👪

I keeo getting these nasty cramps when I run. they are similar to period cramps or cramps you get when you have diarrea.. That is the only way I can explain it. I have always been a runner. I stopped a few months ago because I got pregnant and decided to start up again after my miscarriage. I dont know why I get these really bad cramps but it makes me have to stop running. I almoat feel the need to go poop. Anyone have a similar experience?
