anyone..?😭

Has anyone experienced or know someone who has paranoia about being pregnant even though it's not likely?  This keeps happening to me ever since I dry humped by BF over a year ago and worried I was. But now every time I even touch him over his pants or give him a bj I always think that I'm pregnant or the "what if" question. Is there somthing wrong with me..? Please anyone help ik I'm not ready for sex but it just bugs me bc I can't stop worrying....😔
