Oh my I will pray that God eases your pain and that your baby boy is healthy and delivered on time
I don't have any advice only well wishes and prayers.
I am pretty sure that the first dating ultrasound is more accurate than the date of your LMP - this is because most women do not conceive exactly 14 days after your LMP, which is what would have to happen for that date to be accurate. For example, I know that I ovulate 10 days after my LMP and not 14, so using the date of my LMP, would not be accurate for me.
I can only imagine how miserable you are, but I would try to hang in there. I don't think that the doctors would be delaying labor just because of his size - they must be pretty sure about the dates. It is best for the baby to stay where he is for the next 3 weeks - I know you are hurting but 3 more weeks of suffering is better than a lifetime of suffering for him (and you) if he has any complications from coming early - so try to think of it that way and it may help. Also, I am pretty certain that he would already be addicted at this point - again another reason for him to stay where he is and get a little bigger before birth. Have you discussed your concerns with your doctor? I would be open with him/her.
Hang in there - you are stronger than you think.
Oh, and congrats on your little boys - boys are pretty wonderful
I agree with nola. Just try and hang in there. Remember everyday for your little one is one more day of very important growth. So try it just one at a time. Tell yourself, I'm just going to get through today and then deal with tomorrow. Towards the end, every single day is huge growth for the baby. You can do it!
Praying for you. May God send you comfort and strength in this difficult time
