Any answers would be helpful thank you

Could you be pregnant, yes, since you had sex. That does not mean you are. The signs are also signs for many things, or a sign of nothing. There is really no way to know or tell at this point.

You will need to wait and see if you miss a period or not

Perhaps a bit early but with no birth control, would pregnancy be a surprise? Of course not. Be more proactive or you will be a mother again.
