Help...

Ok so question first then background, question, should I take a pregnancy test or is this possibly normal? So background. I had an abnormal Pap smear in March, came back positive for HPV (my ex husband cheated and this is the result) I had a colposcopy done in May 11, my last cycle was April 22, my cycles are usually 28-31 days, usually right around the 30 day mark. I am now a week late and for the past week I have had loose stools every morning and mid day. At night it's okay. I wasn't sure if a late/missed cycle was normal after a colposcopy or if I could be pregnant.
