Weird stomach issues every cycle since taking i-Pill

Hi everyone, I wanted to ask if anyone has gone through something similar.

About 2 months ago, I took the i-Pill (emergency contraceptive). Since then, my cycles have been kind of off. For the past two months (and now this month too), I’ve noticed a pattern: • Around 15–20 days before my period, I start getting really bad stomachaches, nausea, and bloating. • Once that phase ends, I immediately start getting PMS symptoms, and then my period arrives. • My digestion, which has always been sensitive, feels worse since then. • My cycles have gotten longer than usual.

This has been happening in the exact same pattern each cycle, and honestly I’m tired of it. I never had this issue before taking the i-Pill.

Is it possible the i-Pill has messed up my hormones this much? Has anyone else experienced long-lasting side effects like this? Should I wait it out or see a doctor?

Any advice or personal experiences would really help.
