this could happen for any number of reasons
are you taking any sort of medication?
are you taking birth control methods? i.e.: implant/coil/the pill etc
are you under any sort of stress?
if it worries you go see your doctor or local health nurse
but it should be fine
or had used on you?
(having a flower hairband in my hair) a guy says to me, " that flower is beautiful, but not as beautiful as your eyes"
and the other day on bending down to pick up some shopping bags a guy says to me "like that position your in, it's your lucky day i'm getting your number"...
