As I said in the other thread, I think you should do what's best for you and your body. If you feel that you're not ready, then more than likely you aren't. You shouldn't push yourself to do something that you don't feel that you are ready for and I think it's very infair and selfish of your DH to give you an ultimatum like that, how would he feel if something bad happened to you or the new baby because you got pregnant again so early? I agree that maybe you should go to your GP or OB and discuss it with them and see what they say, if they say it's not a good idea now because a,b and c could happen, maybe that might change your DH's mind, maybe even get him to go with you so he can hear it from the horses mouth.

But please do what you think is best for you, it would be so horrible if doing it made you unhappy, sick or stressed.
