Pregnancy does weird things to us, all those hormones, you're not weird, don't worry. I feel like I have been more clingy to DH since being pregnanct but I think it's because I have been worried after having a m/c and I don't know I feel like I need him around to calm me down!! lol. So I would be just like you if he went away for a weekend I think.

There's been some great suggestions on here, keep yourself busy!!
