Hormones are awful arent they!! Just before I found out I was pregnant I kicked OH out! I was finding every excuse to argue with him and I think I actually enjoyed the arguments

so I ended up kicking him out and then 2 days later I found out I was pregnant!
Luckily he was very understanding and has been overjoyed ever since. But like you say, like most men he has been coming out with the most insensitive comments that sometimes make me want to strangle him!!! He had a case of man flu when i was about 10 weeks pregnant and expected me to run around after him when i felt like shit myself! I was very tired and had awful morning sickness, when I told him how bad I felt, he just told me that loads of women have babies and pregnancy is not an illness, so i should be looking after him! Insensitive git!
Sounds like your OH is excited though! Hope you have a happy and healthy 9 months!
