Mother opposing birth control

So, to keep it short I’m 18, I’ve been sexually active for almost a yr with my yr boyfriend basically my first. My mom doesn’t know I’m active and I’ve tried to bring in the idea of birth control every now and then, but every time she’s always against it even if it is to regulate my period.

Due to stress from work and school plus I tend to not eat or eat loads at times my hormones become unbalanced.

Anyway, I brought it up today and she was completely not having it. The way she sees it is that if a girl gets on birth control is that they’re already wanting to do it with whomever.

My reasoning is that I wanna prevent and regulate pregnancy. I’ve been informing myself about sites to order off of so they can be shipped to my boyfriend’s place or try to set up a doctors appointment in secret to get a prescription. Either way, I want protection and control of my period.
