18 months ttc

Today is 10 DPO and i got a BFN. Thats another month with a negative test. Another month where my excitement was crushed. DH and i had our first appt with a fertility specialist 2 weeks ago and i was hoping to come on here and say "hey everyone just when we decided to see a specialist we got a BFP naturally so dont lose hope!" Like a lot of the stories ive heard recently. Wishful thinking i guess. If im not pregnant then i want to start my period already so I can go ahead and get this HSG test that im so terrified of. On to the next month of trying i guess.
