Depression or just pregnancy hormones?

Just • 2 girls & baby girl no3 on her way 😘
I'm 12w 4d pregnant with baby #2. I'm so emotional, irritable, tired, no enthusiasm to wanna do anything, I'm constantly loosing my patience with my 3 year old daughter. I just don't feel me at all. I've had depression in the past but not while pregnant I just dunno if I'm really hormonal or have a touch of depression. I just know I hate how I feel right now and hate my self even more for how snappy i Am at my daughter. She is going through a stage of not listening. Hubby doesn't help either he is always at his mums and just doesn't gave no interest in pregnancy at all and offers no support or help with daughter I would b better of alone and less stressed as well.
