My period was due two days ago. On the day of my expected period I had light cramping on and off and no spotting. Today I had even lighter cramping and some red spotting when I wiped but it never got on my panty liner. I took a HTP and it was negative. I don't believe this is pregnancy related. At the beginning of my "fertile" week I had passed a kidney stone and was in massive amounts of pain. Could this have affected my ovulation and caused a spotty period? I also got a call from a nurse saying I had "atypical squamous cells" from my pap smear. Could that have had anything to do with it? Should I wait it out or call my doctor? Thanks.
