26 Day Cycle

Anyone here have a 26 day cycle? Ive always had a 28 day cycle for my teenage years. Now 25, starting a few months ago my cycles have shortened by 2 days. Is this normal? I've been off of deprovera for over 2 years now. Now my cycle fluctuates between 25 and 26 days. Also when did yall ladies ovulate?? Hubby had a vasectomy done almost 6 years ago. I do know that they are 99% percent effective. But missed my period today but had some spotting about 4 days ago. A bit nervous and dont want to make a big deal of things until I see my obgyn. Thanxs glow support ladies!
