endometriosis
"I have been taken it for 3 weeks. 
So far, so good! I was put on BC because I have severe Endometriosis and every single day of my life, I would have severe cramps. Period or not, they were always there. SO- I started BC. 
I started the active pill on Day 3 of my last period and it stopped it immediately (that was the plan) which is amazing, and means that it's doing what it should. 
With Endo, my hormones are very out of whack-- so the first few days felt like I was going through menopause. Hot flashes, cold chills, nausea, irritability-- then extremely hungry and happy all in a matter of minutes. For days. It's SO much better now, and I'm very happy to be on it. 
Also, I have no noticeable weight gain! That was my biggest fear!"
