I have been taking yaz bc for 2 months now. When I started taking it the first sunday of my period, it was only 2 days into my period, and the next day my period stopped. Next month, it came on Thursday(thanksgiving) and lasted until the following thursday. Well, I am now due for a period. I will be taking another pill here in an hour, and that is the third white pill. Should I have started my period already? I know there is a 100% chance that I am not pregnant, and that is not my concern. I was just wondering if maybe I wont have a period this month. I would love that, but I also just want to know. I am not stressing, so that is not why I havent started yet. Another thing, I had my house smelling like propane for a few weeks now, and it got worse, could that make a period not come? Thanks for any help.
