Mama Mia is a clinic that has obgyn specialists, drop-in contraceptive consultations, pregnancy doctors and pediatricians. It is located in the middle of Östermalm so it is very central although there are other clinic locations in the city. I have been going here since I moved to Stockholm and all the personnel I dealt with were warm, pleasant, and discreet. It takes forever to get in touch with anyone but, as it is quite a popular clinic, it is to be expected especially in Stockholm. If you are not in a particular hurry, though, their drop in time works best for you.
