Strange Conversation with My Uncle

A family friend died recently and I stopped by the funeral home this morning to pay my respects.  I was talking to my mom and uncle when my uncle asked, "So do you have any doctor's confirmation of the pregnancy yet or do you still just think you are pregnant?"  I was a little wierded out that he would even bring it up, but I told him that I didn't have an appointment for another couple of weeks, but that I was pretty sure about the pregnancy and didn't need to go to the doctor and pee in a cup when I could pee on a stick at home and get the same result.  I didn't mention it at the time, but the fact that I've missed two periods, my boobs fell like they're trying to make a bid for secession from my chest, and my stomach churns any time I'm foolish enough to let it get too empty is enough confirmation for me.  So yeah, I'm pretty certain I'm pregnant.  He just kind of looked at me funny and said, "well, don't you have to get a confirmation?"  I was like, "no, that would be a waste of money and the midwife's valuable time."  He still seemed confused and I wasn't sure if he couldn't believe that a woman would know she was pregnant without having a doctor tell her she was or what.  Finally, he said "I thought you had to have the doctor confirm it.  Every time my step-daughter gets knocked up she has to go get confirmation."  Knowing his step daughter, I'm fairly certain the reason she has to get early confirmation is because she's on Medicaid and they need a doctor's referral to an OB or something.  I'm still not sure what he was so confused about, and now I'm confused by the whole conversation.
