HELP! Could this get me pregnant???

So I met up with my boyfriend today. We got a little carried away today and we humped each other without any underwear on. He didn’t cum near my vagina (he came in my mouth). It was just his dick rubbing on the outside of my vagina.

I wasn’t thinking about contraception and pregnancy at the moment. But I read something that said this action could still get me pregnant.

I also think I should add that I get irregular periods and my gynecologist has told me I have a few hormone regulation issues (TSH in particular) But I know this doesn’t make it impossible for me to get pregnant.

I need your opinion,ladies. Could I be pregnant? I am NOT ready for a baby right now as I am only a teenager. I don’t know how to deal with this. Can someone give me some advice? Has anyone been through this?
