Another Month of disappointment baby no #1

sh
Feeling so desperate. I am 31.Trying for baby #1 and for more than a year. Had all our blood and urine tests done last month.Also semen analysis and semen culture tests. Results are normal. Also i had gone through the painful HSG  test. No tubes are blocked. Only my thyroid hormone TSH levels are touching the higher value. It is 5.47 . And the Reference range should be (0.30 to 5.50) . So doctor prescribed a medicine for controlling my TSH and also a Folic Acid and B6 supplement tablets for 3 Months. I always ovulated on CD 15 ,16 or 17 as predicted by opks and always had my AF according to my ovulation date on time . Never experienced any delay on AF . This time it was predicted for my AF to be yesterday. But it didnt come.And it made me positive and may be this is the month . But no! All positivity was only for a day. I have got my AF today. I feel so sad and depressed as if i wont be able to be a mother. I never thought i have to face this. I feel like to cry. Unable to concentrate. Even my husband do want a baby but he cant feel this pain of disappointment.
