Mood swing advice!!

Hello ladies!

I am seriously going nuts I feel like. My husband is only home for 2 weeks every 4 weeks and he got to come home early because our first ultrasound is Tuesday (yay). The entire time he’s been home my mood swings have been awful and I’ve been so rude I feel like to him and then I end up crying. I’m so nervous about stressing, I don’t want to hurt the baby by stressing too much and I don’t want to keep putting my husband through this. Any tips on how to handle the mood swings better? I’m desperate!
