I am taking beyaz, which are birth control pills, because my menstrual cycle is not regular and I have the desire to conceive a child, the treatment was for a year, I just need 4 months left. I was recommended some vaccines called "Cuerpo amariilo" Each vial of 2 ml contains:
................................. 50 mg progesterone
Vehicle c.b.p. 2 ml .
can I take them while I'm on the treatment or should I wait until the end? And when I do take them when is a good time?
