I think it is GREAT that you are seeking help now. I felt like you did when I found out DS was a boy at 20 week u/s. I was extremely, extremely negative, disappointed, depressed and at times, even disgusted. I could not believe I was gestating a penis inside my womb. And he genetically was my own offspring! But I did not seek help. Instead, I spent the rest of the pregnancy and his first year being depressed and angry. My husband really had to bear a lot!
Around the time he turned one, I started to warm up. And by the time he was three, I loved and adored him entirely. So it can work out!
I agree with a PP, EGD cannot be resolved in weeks, or often even months. In my case, it took years. But has been so worth it. (I know, I would gag when people would tell me this same stuff when I was pregnant, lol!!).
BTW, I had some ick males in my family too. But DS has turned out wonderfully - he is kind, loving, smart and sensitive. I think my DH and myself have played a big role in shaping him into the makings of a great person - and that is a really rewarding feeling.
If you and your family decide adoption is the best thing for everyone, that is a good option. But that is also a complex choice. You have just encountered your EGD - no need to rush into any big decisions just yet. Take some time to mull everything over.
Keep writing here if you need to. You are not alone.
