Prenatal care w/o informing parents

Hi everyone, this is kind of a weird post but I’m seriously stressing over this. I’m 21, a college senior graduating in May, and I recently found out that I’m estimated 11 weeks 5 days pregnant. I am still financially dependent on my parents but I am hoping to move into an apartment with my boyfriend after I graduate where he lives and works. My parents are incredibly religious and judgmental and I’m terrified to tell them.

Simply put, I want to keep my baby but I have yet to have any prenatal care and I want to go in for an ultrasound and testing to make sure the baby is healthy before I tell my parents. I’m still on their insurance and I don’t have the money to pay out of pocket unless there was somehow a free or super cheap option (which for testing I believe doesn’t exist). I have no idea what to do but I really want to make an appointment soon as I am likely almost 12 weeks. I would greatly appreciate any advice ❤️
