Stuck.

I don’t know what to do. Sunday was the day I lost my virginity and I’m not on any type of birth control. I’m 16 and asked my mom on multiple occasions if she can take me. She told me no every time and told me I don’t have that right to my body. I tried to have a conversation with my boyfriend about it but it doesn’t seem like he cares too much. He tells me is my “decision “ and it’s my “risk”. I’m having to do this alone and it’s really scary. Do you think he should help support me so we can both me safe?
