Hello I have found myself in a similar situation. After tracking my flares, I did notice that things got worse just prior and during each cycle. So I definitely think there is a correlation between the two in my experience. Not to mention that I got to a point where I was on my period for nearly 2 months straight. Our RA bodies are sensitive things- weather, stress, and yes, I believe even hormones and play a role in the inflammation levels in our bodies. My gynecologist was able to test my hormone levels and offer me some options to manage my issues. So my suggestion would be to start there. But to really answer your question, yes, I've certainly experienced it too and you are not the only one. I hope your doctor can offer you some help too! -Leanne, Community Moderator
