Started period 2 weeks early...

Bekah

I usually take my pill at 9pm, but lately I've been working really late and when my alarm goes off to take my pill I just turn it off right away and think to myself, "Oh I'll take it later." But I guess I forgot to take it three nights in a row. I wasn't supposed to start my period for two more weeks, but I started yesterday. Is this going to mess up my whole cycle? And if so, will it change my ovulation?
