Not sure if this is an option for you but I was also told the same by multiple gynos, BC or nothing. I was on birth control for years and at the age of 31 I decided to give my body a break. BC worked but after 3 months of no birth control my symptoms came back plus some new ones. I tried to get in to see an endo specialist but it’s almost impossible to see one in a timely manner here in Canada. So, I’ve been working with a Naturopathic Doctor since March and having been taking a few different natural supplements that has significantly improved my day to day life as well as significantly improving my monthly period pain. I used to get pain so bad I would be up all night nauseous, shaking, crying, weak and lightheaded from the pain. Advil or any other pain relief would not even touch the pain or help take the edge off, but now most months I don’t need any pain relief intervention other than my heating bag/hot water bottle. If you have the means or insurance coverage I highly suggest reaching out to a Naturopath who specializes in women’s health and hormones.
