Extremely moody

Hi ladies,

Just curious if anyone has had the same as me or any reason behind it... I’m about 4 weeks pregnant and I’m extremely irritable like literally angry af, I was to kick my partner out just for breathing and my son is driving me up the wall at the slightest misbehaviour which I can usually deal with quite well, why is this so strong so soon and will it ease off soon? 😣 I’ve also had a bit or nausea which isn’t helping. TIA
