Hello, Anon! Thank you for your message today.
Stress can certainly cause period irregularity. Around this time of year, with school winding down and exams, this is often a complaint from our readers. From what you say, there has been no mishap with the condoms, so try to relax and wait for your period to arrive.
Other things that can impact a woman's period, illness, drastic weight changes up or down, a change in lifestyle (like a schedule change or trip) over-exercising and hormonal imbalance, etc.
