I hate the waiting period before testing...grrr...?

I hope you get your bfp! It's odd that you only have a monthly every couple months. A monthly is usually a sign of ovulation, so you might not be ovulating. That depo shot can cause infertility later on. A healthy couple under 35 should take less than a year for pregnancy. You should def. talk to your doctor about your ttc. I hope this month is it for you though!!!!
