Birth Control

I am new to BC! I started taking it a little over a month ago due to a ovarian cyst... I haven't took it in over 2 weeks because my grandmother was in her final stages and my family and I would go sit with her and wouldn't get home until 10-12 at night and I would take my BC at night before bed. I was a week behind and now I am 2 weeks behind I've been told to take 2 a day to get caught up, to wait for my next period, just multiple things and I'm not sure what to do. I need to take it so the cyst doesn't get any worse, what do I do?
