Ok so I've only been taking birth control for a month & 2 days. About 3 days ago, I took it over 4 hours late (on accident!) & had unprotected sex the same day and he finished inside me. The next day I took the pill at the exact time I'm supposed to & so on. Could I still become pregnant? I'm so nervous. I thought that if you "miss" a pill but take it at the right time the next day you'll be fine. I'm on the 28 day progestin only.. (mini pill)
