Could I be pregnant?

Priyana

I’m 15 and I had sex for the first time about 4 weeks ago we used a condom but I’m not birth control but the condom popped on the top but he hadn’t cum yet so there might’ve only been precum or none at all I don’t know... Anyway, I took a plan b and my period came. My period was 9 days early and only went for 4 days. Yesterday in child studies, my teacher told the class how there was a girl who had gotten pregnant but she kept getting her periods... so now I’m worried and I don’t know if I’m just bloated or what but my tummy looks out. Idk if that how a normal stomach should look but after that story my teacher told me I’m so freaked out. Could I be pregnant? And its not like I can take a pregnancy test because of it came out positive idk how I’d deal with it 😭. Someone help :(
