So I am almost 20 years old. And I was in the depo shot for almos 3 years. And I have been off of it for a year now this month and my husband and I have been TTC for a year an I still haven't got pregnant yet and we have sex 2 times a day. And I'm not on birth control anymore haven't been for a year. And we don't use any protection at all and we still have not been pregnant after a year. Is that normal or what do I need to do or change. Please help me.
