Just got my bfp yesterday! 👶🍼😃

Okay. I'm having trouble figuring something out here. Well I'm 18 and i just got my bfp yesterday, which i find super exciting and scary at the same time! Well my mom said to just make an appointment up at the hospital and they'll see me when I'm farther along (I'm only 2-3 weeks according to my test) but my boyfriends mom said she wants to take me tomorrow. And i want all the prenatal care i can get as soon as i can get it. So should i go tomorrow or make an appointment?
