Last month my daughter attained puberty, but this month she didn?t get her period. Do I need to worry about it

Hey friend do not worry about this. it is absolutely normal. few girls after attaining their first period, they might not get their second period immediately or maybe for a year. my friends had irregular periods initially but luckily one of my friend's mother is a gynaecologist and we came to know that this was absolutely normal. she said that "we almost see many patients coming to our clinic thinking as a problem which is actually not. we do say them that in most cases, girls usually get their second period within a year of having their first".
