No I totally don't think you're being stupid. This a new and exciting time, but ALSO a very scary and emotional one too. TBH though...I'm starting to realize more and more that most guys don't get it. I know I said this before, but they really don't have it registered in their heads that we're PREGNANT!! They don't understand the hormonal changes we go through which quardruples our emotions tenfold!!! Me and OH had a HUGE argument last night over something silly, I'll admit I was kinda outta control - I wouldn't back down...I was soooo infuriated. I was like a dog with rabies...hissing and snarling (well thats what I felt like hahaha) but at one point I was trying to get my point across and I said to myself...whoaaa whats going on here, I'm gettin a little crazy....BUT do you think at any point HE would realize oh my wife is acting a bit strange and crazy right now, crap, my wife is pregnant so I should tone it down a notch and not get her so worked up. By the end of it we we're fine (I wouldn't let him go to sleep until we ended it.) I told him that I really want him to read a bit about pregnancy and what not. I acknowledged to him that I was a bit outta control BUT I had a really good excuse for it...I'M EFFING PREGNANT!!! Moral of the story is I don't think your OH hasn't registered the fact that you're pregnant, he may have verbalized it - but he hasn't internalized it...I think that when you guys are alone you should sit him down and talk with him about how you're feeling and what's going on with your body at this stage of pregnancy. Explain to him at this stage of the game it is very risky in addition to the fact we can be quite emotional and we need to be backed up by our OH's!!! See what he says....Honestly I'm going out to find a book or something for my hubby...lol.
Sorry for such the long rant.
