Is it normal to have short cycles?

My cycles are usually 22 to 23 days. I was supppose to come on my cycle on the 30th but it came June 6th-11th. Now I am back on today which is the 30th. What's weird is I have only light spotting. My husband had a vasectomy a 1 1/2 ago so I know I'm not pregnant. It's been 10 years since my cycle has been irregular.Just wondering if I need to see the doctor about this or if it's something that's normal.
