Weird😳

So recently I've noticed a lot of small changes in my life, like for the first interest, I know it's super TMI but I've had a problem with holding my bladder, I've peed my pants 3 times in the last 24 hours, which is super unlike me, I've also noticed a lot of weight gain. I gained 8 pounds in a week, I've also been super super crabby the last week for no reason, I don't think I'm pregnant because I'm on the depot shot, but this is just insane for me, any possible explanations.
