"I've been on this for of BC because I generally get sick on combo pills. I was told by my PCP that it'd help control my cycle and make a bit more predictable. I've been on it for under a month and I'm already not liking it. I started it the first day of my cycle; bleeding seemed to get heavier with large clots (normally med-heavy with very small clots), constant headache, and I've broken out with very painful zits on my chin and forehead (skin is generally clear). Skin is oily now as well. I'll definitely be looking for a different type of BC."
