Starting to lose hope

Hello. I'm a newlywed. But my husband and I have been trying to concieve. He has a five year old so. I have tried fertility treatments and they have not worked. I have to go to the doctors on Monday for an ultrasound to find out what is going on. I was prescribed bravelle and Ovidual injectables. This is our last step before <a href="https://glowing.com/glow-fertility-program">IVF</a>. I'm really nervous. Has anyone been through this or have any thoughts?
