Period Duration

My period usually lasts about 3-5 days (only had 1 period before and that’s how long it lasted) the 5th day I just spot but it’s the fifth day and it’s still a light flow, I have just been wearing a liner and it doesn’t over flow. This is only my second period and I know the first one might not be too accurate for future ones but I just wanna know if I should be worried or not. Thanks
