1st round of clomid failed

Nikki • Ttc number 3 for me and number 2 for hubby! And first child together! 4yr of trying been 8 yrs since i had a baby. Baby dust to all!
The first round of clomid failed. Ive decided not to do another round right now bc doctor says they will only let me do it 3 rounds. I have 2 kids and had them with nothing more then help from metformin but now cant get pregnant i was sure with the help of clomid id get pregnant :(
