Off period??? Help!

laina • 2006 Daughter, 2013 MC
I'm always 28 days, 5 day med to light period. Last month I didn't get my period til 31 days, 4 days heavy. I did have some stress, but not as much as ive had in the past and NEVER missed a day or wonky. This month I'm going on day 30 and still nothing. Any suggestions?
