Can the pill make you miss a period?

I've been on the pill for two months and since I started, I haven't had my February period. We did stop using condoms after I started the pill, but only after I was adjusted to it. It's a poll that takes a week to get regulated on it. I can't afford to go to my gyno it's a 60 dollar copay, so that's not an option right now. I've taken 3 different pregnancy tests and they're all negative. Could my birth control (Lo Loestrin FE) make me miss a period?
