Injectable contraceptive tome (Mesigyna) and my face ...

I have been taking injectable contraceptives (Mesigyna) since June and my face has been giving some balls that look like pimples but they do not grow. It had never happened, would it be Mesigyna's effect? What do I do? Do you have another injectable contraceptive option? Thank you!
Expert answer:

It may be contraceptive effect, if it is really the contraceptive need to stop using. The definitive diagnosis of the cause of your skin lesions should be made by your doctor, the suspension or exchange of the contraceptive (if necessary) should be made by your doctor.
