Getting territorial

Jessie
Is it normal? My husband and I have been living with my best friend (a guy) for over a year, and my husband's best friend and girlfriend moved in temporarily at the beginning of November. I've had some issues with his friend in the past, but lately I'm just over the top and want everyone but my husband gone. When I think about it, I feel like a mountain lion or something. Just super snappy, and just... Territorial. Anyone else get like this? I'm almost 20 weeks.
