Hello. I have had regular period cycle if 28 days from like always. But now since 6 months my cycle length has reduced to 25-27 days. Is it normal? I have a daughter of 2 years old. The flow is normal neither too less nor too heavy. Also I have got immense hair loss since a year. Have tried everything nothing is working. Is periods problem related to hair fall. I don't have thyroid, diabetes. Please suggest what could be the reason and how to cure these problems.
