Going insane

I'm undergoing fertility treatments to get pregnant. I have PCOS and Hashimoto's disease. It's been a challenge. I dont ovulate on my own. So my amazing doctors finally got me to grow an egg, and to ovulate. They told me to test on Sunday... of course it would be on mothers day. Im so close and I'm going crazy. Im desperately looking for any signs. I have taken way too many test, which all have been negative and of course they would be. I know it's too early but that slight chance I could know makes me do it. I want this baby so badly. Infertlilty it hard. It's the most exhausting thing I have ever gone through in my life. This past cycle alone I had 4 internal ultrasound on my uterus and ovaries. I have been on letrozole, ovidrel, and progesterone just this cycle. I dont know what I'm going to do if I get a negative in 3 days.i know I will do it all again, and possibly more, but it's so hard. These hormones are making me so emotional. I just want my baby. I know that God is watching out for me. This wait is just so hard.
