My cycles have just recently started getting shorter. I used to be a 25-26 day cycle and the past couple of times have been 20-21 days. I'm not trying to conceive right now but would like to try for #3 in the near future. Anything I should be worried about? Any way to lengthen my cycle again? I'm almost 2 years postpartum and am 38. My average cycle day is skewed in the picture because of being pregnant. I have my next annual appointment with the obgyn in April.
