I am so glad I found this site. I just switched to Loestrin from Ortho Tri Cylin which I thought was making me break out and have heavy cramps. I have been taking Loestrin for a little more than a month and thought I was pregnant because I am constantly tired, nausea, and moody. My hair coming out a lot more than usual, I am hungry all the time, and I have had severe headaches. I am going to stop taking this pill immediately.
