I would explain to your DH that there is a chance you could fall pg, and discuss the options with him, and make a decision together..

DH and I spent a night discussing the options a few months back, so I could still take the MAP within the recommended time, and if that didn't work, then we might have been having another child.. If you include him in the decision, he may be ok with the fact another might be on the way..

GL whatever you decide and happens.
