I'm On Extremely Scared About What Just Happen Between Me

I'm on extremely scared about what just happen between me and my gf. So here is the question. Is it possible she is pregnant soon ? if my hand had that dried sperm and before i touch her outer vagina from what i know is called vulva i wiped my hand with tissue and we chit chat for around 10 minutes then i touched her outer vulva. Please do help me and for the mistakes i did. Thanks
