14 And might be Pregnant. Please help..

Hi. I am 14 years old. I lost my virginity about a month ago. I took a test yesterday and there wasn’t a line, but I took two just now and there’s a very light line on both.

My friends older sister got me these tests. I have no female figures in my life. It’s just me, my dad, and 3 brothers. I’m terrified to tell my dad I had sex. I read that you could go get a blood test but I have no way of getting to the doctor. Please do not make mean comments. Nobody has ever taught me about sex. My school nurse taught me about my period but she didn’t go into depth, she just told me it’s an egg coming out. I googled all my symptoms and it keeps saying pregnancy or PMS. But I’m not sure and I’m so scared😩 I’m only in the 8th grade
