Hello Dr

I had D&C on 31st May and then had first period on 16th july (ie after 45 days).  But after 16th july,  45 days has already passed, There is no sign of second period. But I feel really uncomfortable. I usually feel wet , as i am having periods. But in actual there is no period.
Having no second periods is a serious problem? Should i worry? Should i visit my gynae?
Please help.
