I'm 14 years old and I've been taking ocells for the past six or seven months, and I haven't experienced any of the symptoms or side effects of this pill. My period is three to five days long, and I'm very light, I've only gained about five or ten pounds, and my heart rate and blood pressure are normal. It does say on the side effects may make you lose or gain weight, like I said, I've only gained a few pounds, which I could easily lose.
