Stomach symptoms flare up without birth control?

Howdy. Not yet diagnosed with endo but my specialist thinks it’s likely, hopefully getting lap this year. Also diagnosed with IBS-D. My question is, has anyone noticed a correlation between not being on birth control (pills) and an uptick in stomach-related symptoms? I haven’t been able to get my refill because I have no car and am not in a walkable area, so I just had a rough period and now that it’s over I’ve been experiencing the biggest flare in my IBS symptoms in almost a year. Multiple days of diarrhea, gassiness, bloating, sour feeling indigestion, lack of appetite, urgency and stomach cramping. I haven’t made any significant diet changes in the past few days, but I have been without hormonal birth control for two weeks. I’d love to hear some thoughts
