Can we say Hormonal??

Last night I was feeling a bit queasy after taking a warm shower but I slept great! Today I have been very "crabby" you might say. Everyone that I interacted with I was bugged by. I couldn't even discuss Christmas presents without being pissy. I was also ready for bed by 5:00 tonight. I am hoping this is due to increasing hormones from a pregnancy not from the lovely progesterone and estrogen!!
