9 months ttc

After 9 months of ttc, I just got my period again, it breaks my heart every time I get my period , I already went to 2 different doctors and they both said me and my husband are healthy, but I just don’t know why it doesn’t happen , I pretty sure we do it at the right time, as we always BD every other day, all along my cycles , the only thing is that I don’t bleed much on my periods, it’s spotting for the first day, second day I get a flow, that fills my pads and it’s the only day, so from the third day it goes back to spotting and then brown spotting and the 5th day it’s finish, what do you ladies think ? Is there any one of you experiencing the same thing , or do you have any suggestions for me, thank you for taking the time to read my post!
