Hoping i still have a chance

Tomorrow will tell. Hpts negative up till 12dpo. Do you think i should have a positive yet? Wish me baby dust please. We have been ttc 4 years. I'm battling pcos and hypothyroidism. :( all i want to do is give my husband a child and I'm feeling less than a woman right about now. 7 rounds of clomid. .. 3 of femara. . Im at my whits end... my next step is iui. But it's really not that cheap unfortunately.
