Struggling to conceive again

Sherrelle

So my last depo shot was June of 2017 I want to say. And ever since I’ve been trying to get pregnant. I already have 4 and it seems like it was so easy with them. Well I wasn’t on birth control at the time. Since I’ve been on depo and gotten off. It seems like it’s so hard to conceive again. Can someone please help me and provide with tips. Thanks!
