BABY MAKING TIME! I need help.

Me and my boyfriend are trying for a baby, but for the past year and a half we have bwen having a hard time. I have bought some pills online call concieve easy and all it did was fool around with my period. I am currently on a 28 day period. When i am ovualting it is creamy and not sticky at all; so to me im thinking that i am inferitle. I was on BC ( shot) over 2 years ago. So..... what are some things that can help me oncrease the chances of having a child? Should i just stop and get tested to see if i can have children? What should we do?
