Irregular cycle

Does anyone else have a irregular cycle?? my cycle would skip a month and come on the next month and it’s starting to worry me because I didn’t come on until the end of December and beginning of January.So for February I came on but it was extremely light and it was light the WHOLE MONTH .Like why am I on the whole month and it’s so light I don’t even need a pad or tampon just a panty liner.It’s like it’s stuck or something and now it’s March and it’s still light.Any recommendations?
