Need some words of encouragement

Last cycle I had a chemical pregnancy and it devastated me. We have been trying for years and it costs a lot of money every try and lots of needles. This cycle was different for the first time in 3 years I started to ovulate on my own this is also the cycle my daughter told her teacher that " my mommy will be pregnant soon with my little sister" . I did my second iui today and everything seems to be pointing the right way but I only have 2 tries left with the clinic and I so scared to feel hopeful.....
