Messed up BC

Abby

I missed a week of birth control. Where I was supposed to be was the second week, but I had to start a new pack to fix the schedule. Is it likely that I will miss my period? I’ve had PMS symptoms but no period, is that possible?

(Bf and I had protected sex about 2 days after my last period and again a couple days later.) but we checked the condom regularly and it was secure. Both times.
