I’m 14 5’7 and very active, going out for runs and playing basketball a lot of the time. Suddenly, other the span of one month i gained 4 kgs even tho I had no change in my already healthy diet. is this a sign of an upcoming growth spurt? (I’ve been growing 3 inches every year since I was 11 and haven’t slowed down if that helps)
sadly my parents are on the shorter side (5’7 dad 5’2 mom) and also my brother is 15 with his growth plates closing at 5’7 if that helps. my uncles are grandfathers and cousins are tall tho, 5’10+

regarding rule 6 I’m not asking abt my final height I’m just asking if gaining weight is a sign of a growth spurt or if im just fat
