So, my period has been a bit annoying these past few months. July and August, it was about 2 weeks late both times. Prior to that, it was pretty spot on every month. Come August and my period didn't come at all. I had it again in October but not in November. I'm 17 days late this month. I think it's all due to stress that comes with wedding planning and other life stress. I spoke to my gp who also said I'm probably really stressed and overwhelmed by the planning process. I planned on going on the pill and wanted to start in a week because I'm getting married in two weeks and I was told I need to take it for a week to be fully protected. Do you think it's okay to start the pill even if my period still hasn't come?
