http://www.medications.com/effect/view/22529 My dermatologist put me on Yaz a little less than 2 weeks ago for acne. I've been bleeding ever since! I'm really getting worried about it and have been debating calling my gyn to see what the deal is. Has anyone else bled like crazy with Yaz?

Then after the first month and became regulated.I originally had a period of about 6 days, but then after I started this new one.. my flow was very heavy http://www.medications.com/effect/view/22529?item=986 Wed, 12 Sep 2007 14:22:12 -0400 http://www.medications.com/effect/view/22529?item=1756 I've been on Yaz for three and a half weeks, and on my period the entire time. I called my doc and she switched me to Lo-estrin, which apparently has lower amounts of estrogen, which may be what's causing all this crappy stuff to happen. Hope this helps!
