I was taking Yaz for the first time last month, and on my week of non active pills, I took a
plan b. I never missed a pill, maybe
delayed by a few hours on one or two times but mostly just on time. It was the first time my boyfriend came inside me so I was scared and took plan b. Not surprisingly, I didn't get my period as expected that week. I started my second pack the day I was supposed to, right after the last inactive pill of the first pack - which was last July 11.
