I'm not really sure but I think I took my last depo shot January of last year. I was having any periods so I took a low dose of birth control pills for a month. Started my periods and have been ttc since then. I've taken prenatal vitamins and folic acid vitamins still no baby. Is there anything I need to take, or do? I use Glow and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> to track ovulation and have sex on the days they tell me too.
