hi I've been on trisprintec for over 3 years now and my periods have always been consistent. My period came today and it wasn't supposed to start until Thursday. I am sexually active but we always use condoms as well as me taking the Bc pills on time. I didn't skip any pills. My period is never early like this should I be worried. I am due to start taking the inactive pills starting today last night was my last active pill it's just a few days early?
