my gf has irregular periods. nothing wrong with this, just that it gets frustrating. Shes 2 weeks early right now... oddly. last month she had a full 4 weeks, which is unusual for her, others its closer to 5 weeks and sometimes not at all..... I wouldnt mind it so much, its just confusing... everytime something like that happens I freak out and think the worst. Anyone else have these problems?
