Okay this is gonna sound like a really dumb question:

So back in February I got supplied 3 months of the Walgreens generic Estrogen ring and I knew I was having interesting hormonal effects because I just had my IUD removed after only having it in for a month.

Fast forward to about a month ago and I got dispensed the Enilloring from CVS, another generic brand.
I’ve noticed that I cannot stop eating for the life of me, a lot of mood issues, and issues with my skin. The last time I had this happen was back in February when I got back on the ring.

Is there potentially different side effects for using different versions? I know it’s the same drug but I’m just curious.
