help asap - 16 and maybe pregnant

taylor
so, i had sex 11 days ago. we used a condom, but he put it on upside down at first and then fixed it, and it may have had some precum on it when he went in, but he pulled before he finished as well. it was my first time, and i don't want to hear any hate for it either, i've been dating him for some time now and it's all okay there... my period is supposed to come in 8 days according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>, but i'm having some pregnancy symptoms and i'm freaked out hardcore lately that i'm pregnant. i'm going to the doctor on friday to talk about birth control, and i'm mainly scared that i'll have to take a test and i'll be pregnant and my mom will be informed... is there any way i could terminate a possible pregnancy at home without my parents finding out? i'm absolutely terrified right now and i'm so far from ready to have a baby, and it's my luck to get knocked up on my first time😅
