Am I supposed to have a period on Slynd?

I’ve (F28) been on Slynd for about three months now. For the first two months I had breakthrough bleeding of some kind every day. Now the bleeding has stopped altogether. I take my pills on-time and never missed a dose.

During my placebo week last month I didn’t bleed at all. I’ve taken pregnancy tests (all negative), and don’t have any other symptoms. My boyfriend and I always use condoms in addition to me taking the pill, so I was never truly concerned about being pregnant. I just had to rule everything out.

According to the Slynd website, I may not experience a period at all with continued use. Some people say to skip placebo weeks but I usually take mine and finish out the pack completely. It’s kind of freaking me out because I’ve always thought I was “supposed to” have a period every month.

Has anyone else had this experience while on Slynd?
