Periods only 1-2 weeks apart?

So I’ve been getting periods that are quite close together since February now. They are either a week and a half apart or just about two weeks. I’m a bit worried if this means I have an infection or something?? Though, I will add that I only first get my period in January so I know this could just be a normal thing as periods are irregular at the start. But I am getting worried as they are quite close together
