Does anybody else here have irregular periods? How irregular is normal or cause for concern? Mine have never really been regular. I've been tracking them for the last year and my cycle has ranged anywhere between 25 and 45 days. For instance, the last 5 cycles have been 29 days, 37 days, 38 days, 26 days, 35 days. Is that normal? Should I ask my doctor about it? Sorry to be asking this here, but I figured that a forum for women is the best place to ask a question about periods! Especially as we talk about so much medical stuff here. I don't know if this is normal or if it's supposed to be like clockwork.
