Advice

Okay so I’m kind of freaking out me and my boyfriend are both 17, I’m on the pill and have been since November but we don’t use condoms. Yesterday neither of us were thinking probably and he didn’t pull out. I’m scared I might be pregnant. There is no way I could tell my family as my sister (20) just had a baby a few months ago and my family is already doing everything they can for her. My period was last week and I’ve been taking my pill but I’m still freaking out.
