My daughter just started her period 2 years ago. Sometimes I get my own period, then get one when she gets hers ( same days). I just wondered if any other moms went through this. Is it because im in perimenapause or just a coincidence? I was pretty regular until 2 months ago...now no period at all.. im 48 and not pregnant....lots of symptoms ( migraines, mood swings, crappy memory, etc).
