Can you get pregnant if your heavy?

Sorry I'm new to this app

I'm just trying to answer the questions I have like...

The fact that I am a big girl and I think I might be pregnant. And I have come to this due to the fact that lately I can't control my emotions (like I'm not going into detail but just please I'm not being dramatic like I'm litterally worried), I'm constantly throwing up my boyfriend got me some sausage and egg and the egg as soon as I put it in my mouth I was running to the bathroom! And the smell of popcorn this afternoon about made me run for the garbage can ...but I'm over 350+ ....could I be pregnant? I would just go to my doctor but insurance issues rn unfortunately 😑
