That's horrible! Like i want to do that too and my parents are against it too but they aren't being assholes about it bc they know how tough pregnancy is on me so they being supportive even when they are against it. Honestly if you are OK with it then I def would prob cut them out. You don't need that kind of negativity.
Your body, your choice. They don't get a say in that and they are being terrible at "punishing you" while you ask for their help. I'm very sorry you have to deal with that. And yes I would take a serious distance with them after this. Hope you can find help somewhere else.
