I am one week late which is VERY abnormal. My cycle has been steady and always on time since I first got my period. I always have protected sex but for some reason I missed my period... and I have already taken two tests and they both said negative. Im not under any new stress just normal stuff. Although I am taking a new medication called aciphex for heart burn... could that have anything to do with it?
I'm having no symptoms just a little bit of a bloat and gas.

Please give me your opinions!

Thanks.

Your period may just be off this cycle... give it another week and see what happens. You could try another test at that time, or wait until next month for when your period would be due. It sometimes happens that women may skip a month for no obvious reason.
