birth control
"Started depo when I was 18, never had a period after, stopped taking it when I was 24 to start a family.  It took 4 months for menstruation to start again and only 3 months after that to conceive.   After pregnancy I was put back on, got 3 series of shots before we wanted another baby(no period in between).  Only took a month for my period to return and another month after that to conceive. Also, after this pregnancy I started the depo again. I was 6 weeks postpartum and got the shot while on my 4th day on my period, (which usually lasted 7 days) the next day my period stopped. It is my go to form of birth control!"
