Me and my girlfriend had protected sex about a month ago but we didn't finish so I had to finish on my own by jacking off. She's two weeks late on her period now and it's making me really nervous since she is sort of showing symptoms especially today ( mostly fatigue, she noticed her boobs has grown, and headaches ) is it possible she's pregnant even tho it was protected and we didnt even finish?
If it's protected sex and you both didn't come while still doing it, then I'm sure she is fine. It's possible that she could be getting sick. There are many reasons to why a woman's period is late which includes stress, gaining weight, difference in activity schedule, hormones changing, and sometimes being sick (minor or severe). Her breasts could be growing because she isn't done growing yet or possibly something else which you both don't need to worry about much. If there was continuing pain or other problems, then it would be best to see a doctor about it.
