Hi. I Am 21 Years Old. I And My Gf

Hi.
I am 21 years old. I and my gf had sex on 10Dec.we used condom. My penis was not fully inside of her. It was just haf of it inside. I ejaculated when my penis was inside. Later i took out it and wore another condom.
When i was putting it, i used same hand by which i took out previous condom.
So i am asking that, could it make her pregnent?
She is maybe missing her periods. Her periods start dates are as on..
Oct 24

And in December it had to be 21 but she has not got her periods till yet..
Is she pregnent????
