What should I do? Me (f20) and my bf (m21)

Okay so im on birth control (Depo) and me and my boyfriend have raw sex all the time. My birthgiver (my mom, we don’t have a good relationship so that’s what she’s getting called) snitched and told my grandma me and my man been having raw sex. She’s like oh use condoms or don’t do it at all. And just was basically really upset. That’s the thing tho. We’ve had unprotected sex and he’s came inside me like 3-4 times and no pregnancy. What should I do? I was thinking on just having raw sex and only letting him finish in me for special occasions. Idk but I’ve never any signs of pregnancy or anything.. What would you do
