We answered this question already for you today in an earlier post.
Did you have sex ed at school? If not, it's a good idea to study on your own so you know how sex and the human body works. You can read books on this or search our own site. This will eliminate a lot of stress than the unknown can cause.
A woman cannot get pregnant unless she has unprotected sex (naked) with ejaculation. She would also have to be ovulating or be within five days of ovulation. Sperm will not travel through a layer of clothing to impregnate, not will it transfer from a finger that has been washed and dried.
So a pregnancy cannot occur from what you did.
It doesn't appear that you understand how sex works. Please educate yourself before you continue any kind of sexual activity.
We can't say why your period is delayed but it could be stress as you mentioned, or a change in hormones this month. It should be along soon.
