Secondary subfertility

Rather nervous as I'll be seeing my fertility specialist today. It has been a month since I started seeing him after 4 cycle of failed clomid. After 1 mth of tamoxifen with my new doc and all the investigation from SA to HSG, I'm normal.... If there is an answer to my problem, at least there might be a solution? I feel my journey to have 3 kids seems to be in a blind-folded path.... Should I give up and try normally? But it has been 1 year of TTC after my miscarriage. It seems so hard to get preggy when it was so easy the last time......
