Day 32, no period and neg preg test!

I'm on my day 32, have terrible cramps, sore boobs, mood swings, but NO period. My periods usually comes every 26 days. Had a mc and had a d&c done june 13 and already had one perfectly normal period. We were told to wait 3 periods before we ttc so we weren't trying at all. We did have sex but dh pulled out (tmi, i know!)
Should I be worried? Could it be that mc altered my cycles? Could I be looking at pregnancy?
