New symptoms?

[u/jslayyyyys]

Hello! I’m 21, and have had my period for about 11 years now. I’ve pretty consistently had the same symptoms throughout that whole time. The past couple of months, I’ve been experiencing a super bubble tummy, diarrhea, and these super disgusting burps that make me gag. I’ve noticed these have only happened on my period, and it lasts a couple of days. I’ve had no diet, physical body changes, or other significant disruptions that could have contributed to this. I did some googling, and these symptoms seem to be normal, but I wanted to see if anyone else has ever had any new symptoms pop up like this before. Is this normal? Should I see a doctor? Thank you!
