Frustrated

I had been on birth control for 8.5 years. Depo shot for 5 years and then switched to pill. I took the pills consecutively so I would never have a period. I quit taking bc in January and my periods resumed in February to a 5 day cycle and come like clock work (prior to bc they were 7 days and irregular) so we have been trying for 7 months now and nothing..I’m 26 and I don’t get why some people just get pregnant like crazy and I feel like my body isn’t working. My cycle is clockwork so what is going on?? 😢
