It's definitely possible for a girl to get pregnant even if the guy uses a condom. One key piece of information here is: When did you put the condom on? If you inserted your penis in your girlfriend's vagina before putting on the condom, it's possible you impregnated her. That's because pre-ejaculatory fluid ("pre-cum") can contain sperm. If one of those sperm got loose and found an egg, it would make a baby.
The only way to tell for sure if your girlfriend is pregnant is for her to take a home pregnancy test. I recommend she do this first thing in the morning, when her urine is the most concentrated.
You are correct that stress also can cause a woman's period to be late --or to skip a month altogether. There are many reasons for a woman's cycle to become irregular. Pregnancy and stress are two of those reasons.
By the way, I applaud you for practicing safe sex. Even if you believe you already know the correct way to use a condom, I suggest you look over this brief information about it from WebMD on how to use a condom
. Correct use of a condom can increase its effectiveness.
Wishing you all the best!
