What do you wish you knew? What helps you get through it? What's the most painful thing?
If you got a bfp...do you have any feelings about why, or what helped make it successful?
Going through <a href="https://glowing.com/glow-fertility-program">IVF</a> now! Almost done stimming. Learning a lot and hoping for the best. Thanks in advance for your advice.
