fears over settling down as a woman

This is really weird but does anyone else have this irrational fear… that you might fall in love and trust the person enough to become intimate and end up losing your virginity but regret it, and as a consequence like a religious punishment God will give you an unwanted pregnancy but you’ll grow to accept the situation and grow attached just to have some incident where one thing leads to another and you end up miscarrying your child so now you’re grappling with this heartbreak of losing trust in a meaningful relationship, religious guilt over premarital sex, and grieving your unborn child and it’s something like that… worse case scenario… that drives you away from pursuing a romantic relationship because you jump to worse case scenario. Or even if the pregnancy was successful, then there’s this anxiety over being a good mother and partner and taking care of the household while trying to balance your own needs and your career and how you can’t do it all. Is this weird? Like strange spirals over settling down and having a partner and children? Because it’s a pretty frequent thought and unwanted because then I feel deeply saddened over it like what losing a child is life and how I would cope and how that would impact my relationship with any future partners. I am literally a single virgin - never been in a relationship of any sorts and extremely sheltered. This isn’t even relevant to me but it’s also why I’m like, a relationship is not for me even if I want it because I don’t trust myself. Also the factor of struggling with religion and navigating my career where I feel as though I can’t do it all. How to be a working mother and wife? It’s irrational but it’s something I do think on more often than I’d like.
