Will calisthenics make me gain weight?

Nina Asked: Will calisthenics make me gain weight?

I've been doing 30mins of it for 4days now, while eating extremely healthy and having a decent calorie intake (not high, not low).

But I weighed myself this morning and my usual everyday 140 became 142. So i'm wondering if calisthenics will make me gain weight, like muscle weight for example. I really want to lose weight, I don't want to gain muscle weight.
Could this be due to something else? (I should have my period by tomorrow, maybe its that)
