So me and my boyfriend had sex for the first time (for both of us) on Dec.23. I was supposed to get my period on Jan 5th and its Jan 7th now. Sometimes it's late though. At first when the condom was still rolled up he went to put it on and realized it was upside down and than flipped it over and put it on. My concern is that there could have been pre c** on the condom. He missed getting in me the first time and went to high and too low so maybe than could have wiped it off. Also he only went in about 2 inches because it was pretty painful. What do you think my chances are? I'm paranoid about it so I'm worried my periods not going to come due to stress and than ill tell my mom and ill end up not being pregnant at all and will lose her trust.

Additional Details
Also I'm not positive that there was prec** on the condom
And I don't have my license so I can't go get a pregnancy test :/

Just be aware that no BC 100%, especially condoms, regardless of what the events are.
Try not to worry too much for now; 2 days late is nothing.
No one can predict whether one little sperm found it's way inside or not... stating a probability isn't very meaningful.

Worry will always be part of having sex when you aren't trying to conceive. The pill has a much much higher safety rate. I'd wait on sex until you can get on it.

I am sure you know of course that condoms are not 100 percent effective, so even if everything worked right, it can still happen, they only lower the chances, a lot.

Women using condoms and birth control, have gotten pregnant.

And you need to see about getting your license, since if you are pregnant, you will need to drive to the doctors, latter take the baby to the doctor, and to go to work to pay for all the bills.

Does the boyfriend work, will he be able to pay child support if it happens.
