Urgent Help Please

Hey. So I'm 17, I'm on Alysena 28. Honestly it's been horrible. Weight gain, depressive mood, heavy periods (and I'm severely anaemic), list goes on and on. I'm switching after this pack (3rd month). However my period should've come yesterday. It didn't, and it still hasn't come today. 
I had sex with my boyfriend 4-5 times this month, but it was ALWAYS protected. The condom broke twice but we put another on immediately. He never cums inside me even with a condom.
I haven't missed a pill, although sometimes I am a late (I forgot to take it before school so I take it after) same day.
I had white discharge but no other symptom of pregnancy. I'm so scared. Any opinions on what's happening?
