Could I be gaining muscle?

For the last 6 months, I have been exercising using a treadmill. But since the weather has gotten warmer, I've started swimming and keeping the treadmill routine going on days where it's not so hot.

The day after I swam for the first time, my lower back, arms and the back of my legs hurt really badly. I don't usually use those muscles when I'm working out, so that explains that. However, I stepped on the scales a few days afterward, I gained half a kilo! I have been eating normally and have had no changes to my diet whatsoever. Could I be gaining muscle?

    You cant gain 0.5kg of muscles in few swims. Besides that weight is normal weight fluctuation.

    When muscles are healing from exercise, they swell with water. Your weight gain is simply temporary water weight. Muscles require a surplus of energy to grow, you cannot grow muscles if you are eating a deficit. It is also extremely hard to grow muscles as a female.
