Am I okay?

Summer

Last month, I missed a pill and started bleeding mid-month after I had already had my period. Now this month, my period was supposed to start Wednesday and I haven’t had it at all. I am sexually active, but I’m on the pill and use condoms. I’m just really paranoid because I really don’t want to be pregnant. Does skipping periods happen when you bled for two weeks the previous month? Help I’m a little new to the game! Lol
