My girlfriends period is a week late. Even though there were no incidents that could cause her to get pregnant i can't help but feel insecure and preoccupied. She hasn't shown any sort of symptoms though she's feeling a bit needy. Her period might be late because it's been a very stressful month for her but i'm still very insecure and fearful. Can you tell me if i'm just wasting my worries and that there's no problem or is she actually pregnant ?
