Late period PLEASE HELP

Georgia
So usually my period starts Thursday morning, but I woke up to nothing. It's 3 a.m. I've been taking my pills every day except for one day this month, but I doubled up the next day. My boyfriend and I don't really use condoms anymore, but he pulls out with enough time that he has jerk it out a bit before he can finish. I've been on the pills for probably a year and a half, but I'm afraid this time it failed. So far I've felt bloated, emotional, and hungry, but I always do during PMS. The day before yesterday I felt like I had to throw up, but idk because A, the flu is going around at school, and B, I was working out hardcore really early in the morning with no water or food in me. What do you guys think.
