frustrated and sad, need some support...

Hi everyone I am new to this board. My husband and I have two beautiful children. And have been trying to have our third for about a year and a half pushing closer to two years. I only have one tube and ovary, severe endometriosis, and constant ovarian cyst, plus thyroid problems. My doc finally got my thyroid under control hopping that would help with my fertility. But no such luck. I really got my hopes up this month. I normally have a 28-30 day cycle, and i am 4 days late. So i got all excited my husband was ecstatic just at the possibility . But this morning when i went to test i got that ugly one line. And my heart felt like it instantly broke. I hate hoping and thinking finally then just having it taken away. But i still haven't had my af. Just had some very very light on and off pink sp. But not even a need for panty liner. So hopefully af will just come so we can try again. Well i would appreciate and enjoy any comments and support. My family and friends don't really seem to understand. If there husbands just look at them there preggo. So its a bit hard or they are pregnant. Thank u for reading my post and best wishes and lots of baby dust to all of you!!!!
