Feeling down.

Since we got pregnant 12 weeks ago we are barely having sex. I don’t start things he always has. I’ve asked him he says it’s not on his mind right now. While we were trying I loved it was having it all the time prior to fertility treatments we would have it like twice a month we don’t live together but I’m at his place often. Also he has had some health problems so maybe he’s worried about that and seeing me sick a lot these couple of weeks maybe Dosent wanna cause of that.

Is this normal?. I’m going in for my 12 week ultrasound today and I’m feeling so down spent a couple days with him and nothing and I really wanted to. Anyone else going through this?
