Is it true that you only grow another 2-3 inches after you've had your period?

not really. women tend to grow at an earlier age then boys. it starts around the age of 11-12 (sometimes earlier or later depending. everyones different."women tend to lose out in the height race towards 16 while men keep going till about 21 which explains why they seem to end up taller even though you started out a giant next to them. an avergae height for a woman can be between 5'2" or 5'11". (there are a staggering amount of women that are now breaking that average which is quite interesting. periods don't normally determine height. that's up to your hormones and your pituary gland which controls the release of growth hormones in your body. the only thing you have to worry about with your period is anaemia. keep your nutrition up and you should grow far beyond 2-3 inches (another indicator of your maximum height is to look at your fathers height and your mothers height. high chance you'll end up an equal to them or between them.) hope this helps.
