Hi there, guilt..I know all about that, but really what does it help? There is nothing you can do to change the past. It sound you have a very supportive DH. Embrace him, your love and connection are really important in this phase. IVF can take a lot out of relationships. Since I had a horrible reaction to first IVF and ended up in hospital, my family doesn’t understand why we’d try it again. So I stopped talking to them about it, but this leaves you isolated. There are many success stories and many women who stayed strong through IVF. This forum is my way of expression and helped me cope up. The women here are my support system. My suggestions to you, get support from people around who understand you, take good care of yourself, do things that make you happy and understand your treatments and options.
Regarding DHEA, it is a natural supplement that decreases with age in your body. If taken 75 mg daily 7 weeks prior to a cycle, it can increase your follicle number, but before you take it consult your RE as some women have reported some side effects. All the very best to you.
