s under a lot of stress ( from school, work, and especially if she is worried about being
pregnant ) it is not uncommon to skip a period, or have
irregular periods. I have had my share of scares in the past, and have skipped and have had irregular periods from the mental stress that thinking being pregnant can cause. I would tell her to keep calm and try to relax as much as possible until she can take a test and know for sure. I wish you both the best and hope everything goes well!
