For the past week I've noticed sometimes when I start the truck it makes a little click/hesitation and then starts fine

Today it clicked 2 times and then turned over and started fine

I'm thinking it needs a new starter but wanted to see what you guys think before I go buy one, would like to take care of it before I get stuck somewhere

I just put in a new yellow top optima battery about 3 months ago
