I recently stopped using Levlen ED and switched to Yaz. The doctor told me to take the rest of my inactive Levlen pills before switching to my new pill, but as I had only just started a new pack of Levlen and I was having issues with it I didn't finish the packet and started on Yaz the next day. I didn't tell my doctor or Pharmacist that I did this. They told me to use back up contraception for a while but I forgot and had unprotected sex after being on it for 9 days (there was ejaculation). This was during my fertile part of the cycle as well. There are four inactive pills in my pack, I am up to day three and haven't got my period yet. I don't take the inactive pills because you don't have to. I also ALWAYS get cramps before my period and I can tell when it's going to come but there has been none of this. On Levlen I used to get my period straight away. I have been having some nausea and tiredness but that could be anything right?
Sorry it's a bit of a novel!
