Kinda nervous ...

Alright so my parents are very religious and I’m scared to tell them I’m pregnant again. They believe no sex before marriage. I’ve already had one son and I’m afraid they are gonna be so mad at me. I’m 23 and have been with my bf for a year and half. I know I’m an adult and can make my own choices but I was told this past year that I’ve had a miscarriage and I had a tumor (no cancerous) that it would be hard to have another baby. So for me I’m so excited.
