Could it be?
Thu, 10-30-2003 - 10:11am
I'm on cycle day #35 usually 28-30 and get AF took two hpt and both neg.,but feeling icky and bbs are big and tingly. I have recently started a kickboxing class and am wondering if that could cause my period to be delayed, but usually get AF like clock work does anyone have any answers or am I obsessing?
