I'm late!

According to Glow I was suposed to start my period on the 9th and its now the 11th..I was on the Nuvaring for 2 months to try and regulate my periods and ive been off of it for a month now. I was pretty irregular for at least a year and a half before I was off and on birth control but all forms of bc make me so sick! my point is, this is my first month off bc and I'm late, is it harder or easier after bc to conceive when I was irregular before? any ladies going through this same thing with me or had something similar happen?
