I'm 11 days late, it has never happened before. I was having symptoms of periods but they didnt come. Some doctor suggested me to take "divery" to get my period started but im not sure whether i should take it or not. I checked my test 4 days ago and it was negative. I dont know what to do. In the early days i felt tiring and exhausted and also 2% nauseating but then i felt nothing but no periods. What should i do? Can i still be pregnant or im not having my periods due to some other reasons.
