I've been on the pill (Junel) since July 7th and me and my boyfriend of almost 3 years had unprotected sex the day I ended my first pack. And on the 6th of this month we had sex again and he came inside of me and my period was supposed to start the next day and it still has come. Two days ago I noticed this light brown discharge and today I still have it with a little blood in too. I'm used to my periods being late. What should I do?
