I don't want my horomones to go crazy!

I'm naturally a moody person in the first place, and I always try to stay aware if I am having an attitude even though sometimes It just goes over my head. So now that I am pregnant, I'm scared I'm going to turn into a raging bitch.
My boyfriend and I already get in our share of arguments and I hate it!
I can't tell if some of the stuff he does or says really does bother me, or if its just me being pregnant.
We got in a HUGE fight today, and it's the first night I havn't slept in the same place as him in a long time...I know it's probably good to take a breather, but I miss him so much! He doesn't hurt me or anything..but he got really mad and wouldn't give me my ultrasound pictures I got today, the first ones I've ever had.
I don't know if he ruined them...I hope not...
Things should be better tomorrow...
I'm not blaming eveything we fight about on him, but at the same time I certainly don't believe it's all my fault either.
Hence the, "It takes two to tango"
e's not usually like this...I just want us o have a happy family.
We're both so nervous and happy and scared and excited..I understand it's alot of emotion for the both of us right now.
Anyone on here can relate!
Well it's one in the morning here, I better get some rest..
