Pregnancy blues?

Kristy
I'm 4 months pregnant, with a seven year old as well. Husband is a pretty social guy, which I never had an issue with beforehand. He works hard and deserves some downtime. I trust him 100% and am not at all the controlling type.
Well as of late my hormones have not taken a liking to his frequent outings/drunken homecomings. Not to mention he's a grouch/negligent when hungover the next day.
I get he's trying to let loose while he still can, but it's super frustrating when it's literally every weekend, and some weekdays when he has free time..while we're at home collecting dust. 
Anyone else deal with these feelings of prenatal isolation/anxiety/depression while husband is being care freakin' free? How do I fix this without being a nag?
