I was recently prescribed Lutera and was told by my doctor to start taking it the Sunday after my next period, which was supposed to start on Feb 13th. That same day, my boyfriend and I️ had sex and, just my luck, the condom broke and we had to buy Plan B. Anyway, today I️ started my period ten days early, but I’m not sure if its just from the Plan B or if it’s actually my period. With tomorrow being Sunday, should I️ start Lutera or wait?
