What is wrong with me?!

Pr

Omg I get the most uncomfortable, tight, tender cramps in my abdominal/uterus area! It’s not every month but when it happens it sucks so bad! Been happening the last few months and never before I had my kid. He is now 20 months old and so things should be back to normal by now. I’m about to make an appointment to get everything checked out but does this happen to anyone else?
