S550 jerking while pulling away

I recently bought a 2017 Mustang GT (mt) and I’ve been having this weird issue pulling out of junctions or roundabouts. If I’m in first or second gear while pulling away after stationary or slightly rolling, my car sometimes jolts repetitively while on slight throttle. The only way I can seem to stop it is either shifting up or pressing and depressing the clutch again. It only happens sometimes, so I’m wondering if it’s just a skill issue where I’m holding a slight bit of clutch without realising, or if it’s just a quirk with the car. Or alternatively, maybe it’s something I should get looked at.
