need opinions

So my boyfriend and I just started becoming sexually active, and I’m not ready to be a mom right now. I’m barley 17, my boyfriend is 18 going onto 19. I’ve never felt like this before. Before I had the most craziest baby fever, and even got pregnant in my last relationship but sadly had a miscarriage. My parents trust me so much, and I don’t want to lose their trust, they want to see me do good, and a part of me wants to go on the pill but I’ve heard that when you get off of it, you have trouble getting pregnant, and when you do get pregnant, it could lead to a miscarriage is that true? My mom also believes that, so I don’t think she would want me to get on it. I also have been very afraid to even ask her if she’ll consider it . I am going to go to the doctor because I do have really bad cramps and heard that birth control does help with that and maybe my mom wouldn’t have a problem with it if she knows it’s for my cramps. My boyfriend and I don’t like using condoms. We’ve been using the pull out method. MY QUESTION IS DOES BIRTH CONTROL HAVE LONG LASTING EFFECTS AFTERWARDS??
