14 and maybe pregnant 😓

I’m 14 and I might be pregnant me and my bf didn’t use protection in the beginning but then I got my period and we both decided to start using so than about 3 weeks ago was the last time we had sex and we did use protection which was the first time having sex after my period and obviously he came but last week I spotted and I checked my calendar and I get my period tmr so I was a week early and today I’m still ovulating and I’m scared idk what to do and I don’t wanna tell my mom unless I actually am pregnant but I’m having anxiety because I’m 14 ! And Ik I’m to young to be having sex but things happen 🤦🏻‍♀️ my bf has been really supporting Today he said tmr he’s gonna go buy a pregnancy and I’m stressed and scared I’m still a kid and if I’m pregnant I’m gonna be a kid raising a baby me and my bf are nowhere near ready for that and my mom had me young and she always tells me how she wants me to do better and become somewhere so even I was to tell her about this her heart would literally break I’m so scared you guys what should I do ?
