Hi I'm 21 years old and I started cerazette in July so it's been almost 7 months on it. I experienced no bleeding for the first 6 months and in December I got extremely heavy bleeding with cramps. It felt exactly like my period and lasted 7 days. I thought it was related to pregnancy and got super worried and took a test and it came back negative.  Then I got the exact same thing in January and after 5 days I have bleeding again. Idk why this is and I'm very worried. It's very frustrating bleeding and not knowing when it's coming. I used to have heavy periods before going on the pill and thought the pill would solve this problem, but the pill not only makes them irregular but is the exact same. Any ideas what to do or if others have experienced this.
