Ugh felling defeated

So we have been ttc for a year now I have been on clomid for 6 doses (6months) the last two being 100mg I took a test today (AF is due to come tomorrow or the next day) and it was a bfn. My dr doesn’t know what is wrong so he said if this round didn’t work then I should see a specialist. I made an apt for next Tuesday. I’m so heart broken and feel like I’m letting my family (husband and our beautiful daughter) down. Our little one asks for a sibling. I’m tired of telling people ya not this month and ya we have an apt with a specialist. I wish we never told anyone we were trying. So tired of “well just stop trying” ok ya let’s just stop trying with no real answer to why am I having such a hard time.
