My 12 year old daughter had her first period in February really close to march she recently came up to me and told me that she hasn't had her 2nd period is this normal?

You're really a mom and don't know this?

Don't worry...
If she started then her period will be all over the place.(not literally)
So you can't really predict when her period will be next as she only started.
When I started my period the gaps were bigger than got smaller and sometimes you get your period in the same month. I know its worrying but my mum confirmed it with my doctor.
It will take a 2/3 years for her periods to settle.

Or maybe it could be infection
Cause my sister had the same problem we went to the doctors and found out it was a infection
MAYBE it could be the same thing

It's normal. Don't worry.
