I will be 33 this fall and my husband is 33. We have been married for almost 3 years. And trying to conceive for 4. I have 2 children already, live births with no complications. But my husband doesn't have any children. He has never gotten anyone pregnant to his knowledge. My Obgyn says it's not me, but my husband who wants this baby more than me, has still neglected to go and have himself checked out. What do I do???
