I'm 20 years old and have been on yaz contraception for a few years. 2 weekends ago I had sexual intercourse with my boyfriend without protection. It was irresponsible but he did not ejaculate. Neither less I took norlevo the next day because I panicked. Now I've taken my third inactive pill and my period has not yet started, so tomorrow I drink my last inactive pill. I'm a bit stressed that my period has not yet started but I also know that norlevo can delay periods but does it also apply if you are on the pill and only get withdrawal bleeds? Should I be concerned? I did experience the weekend that ended yesterday a bit pms.
