Wanting to get pregnant!!!

Hiiiiii!!!! Im super excited to be in this little network of women/couples who are trying to get pregnant! Let me tell you a little about myself... So i have a 2 year old who is turning 3 in August. My fiancee and i are wanting to get pregnant! I was on the RODs for maybe about 6-7 months and took them out in early May 2017. We have been trying pretty much ever since they came out. We havent been successful which is probably why i am here to see if there is anyone out there who could relate? What advice you may have? Should i worry or should i not? 😊 thanks! Xx
