I started my pd 10 days early I have NEVER been off cycle. I am TTC right now with hubby and 2 yrs no luck . Not on bc nor have been on bc except for 3 mos b4 i got married. Very scared any thoughts of why?

Hi,
The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. Ten days early is extending the variable range.The rise and fall of levels of hormones during the month control the menstrual cycle. I guessing that a change in your hormonal balance may be the cause. If you continue to have irregular and early periods, call your doctor. If you are very concerned, give your doctor a call now.
