Broken hearted

So I finally heard from our fertility doctor a little while back. We did the sperm aspiration and the doctor said she found 8 sperm. At first we were like ok is that 8 million, 8 thousand or 8 hundred. Turns out she meant 8 as in 1,2,3 and so on. She seemed optimistic but she is a doctor that gets paid only by people going through IVF. So we also went to our primary. Turns out that most men produce 800 million and if she had told us 8 million then chances were decent that we could conceive but being only 8 he recommended that we not continue because out of the 8 the fertility doctor only saw a few move. My heart today is so broken. Everyone on Instagram is announcing pregnancies and births and I'm so happy for them but at the same time I just want to curl up and cry. We don't know what to do now. Do we continue and pray that we have a child we both want so bad or do we walk away? I just don't know anymore.
