Should I be worried?

My cycles average 27 days. Shortest ever was 24 days and longest was 30 days but usually 26 27 28 sometimes 29.......im 13 months pp and we've been ttc for 2 months but ive cycle tracked for the whole year and I'm cycle day 32 and no positive test no signs or symptoms of either pregnancy or period coming.....so should I be worried....even before my daughter my cycles were shorter.....had two cycles a month for awhile......help???
