Contraceptives

Saralee

I have a regular period but since I use Mesigyna (idk how it's called in English) I have problema with my period. I have used this only for 2 months, my last cycle lasted 35 days so I want to know of this is normal when you are taking contraceptives, or directly this injection? Because I thought that it was normal because my body is not accustomed yet. What do you think?
