the medication could be making you miss your period. If you lately started, then I have a sneaking suspicion that that that's the cause for missing them OR possibly your just gonna grasp it late. I indicate you said you have the cramps so its possible, but if you miss it another week, after I would call hindmost your doctor and request an appointment, if they tell you impossible to tell apart thing, consequently get another judgment,, you don't want to mess up your insides.

i've heard that some times a pregnancy question paper can be wrong and being pregnant lacking knowing it.
But others, period is only just missed for different reasons... stress, person worried about something or human being on a diet.
Some others you can have a psychosomatic pregnancy for mistrust of being pregnant and have the same simptoms.
