Ladies I see in the cycle buddies wall and some times in this community too that everyone I have seen who posts their cycle has week long periods or at least 5 days. I am TTC and I only have 3 day periods. I mean is this normal? I feel like I am the only one. I jave read that 3 days is considered norm but please tell me I am not the only one who has 3 day AFs?!
