TTC - baby number 1 I'm 19

Hi girls I'm 19 and TTC baby #number1 I recently had a Miss carriage on the 18th December 2016, tried again straight away but no luck didn't think we had intercourse the days I was fertile that month, so just let me period come and bought a clear blue ovulation test also been using this app so tried everyday I was supposedly fertile! Next period is due 10th feb I'm just hoping for a miracle as everyone keeps saying the more I try it won't happen! But I'm staying positive, would love to hear from everyone trying 😘
