hi,
i've been on petogen for four years non-stop, going regularly and on-time.
recently i discovered that the chemist has been, at times, replacing the petogen with depo provera, and now i started with my menstrual cycle again.
my injections are up-to-date according to my dating cycle, but i am concerned with an unwanted pregnancy, especially since i'ce been i've been unknowingly mixing two different types of injection.
should i take another injection?
