Pregnant

Okay so I’m 16. And I had unsafe sex and I think I’m pregnant. It’s all over the school, I told my best friend someone who I thought that I could trust and she told my ex, who then told a bunch of other people. My ex still thinks that I cheated on him so her telling him made things so much worse. I’m a total fuck up and I’m so scared to tell my mom, what do I do😭😭

Edit- what’s the earliest I can take a test and have it be accurate?? It happened about two weeks ago. And how do you guys feel about abortions... I can’t be a parent and I would feel horrible if I did go through with one but I cannot have a baby...
