First Time Mum: emotional roller coaster

Im accepting my first child in June. Im 12 weeks on Sunday, and it's been an emotional roller coaster.
Im finding that I am very emotional more than what I am normaly, which is normal from what I understand. But Im finding myself being very very homesick, and wanting to go home to my family, to mum. I've been crying all afternoon and still very teary.

I can't stand food atm, and finding it very hard to eat. I have had no cravings, or any desire to eat food. Im finding it hard to be close with my partner, Im very cranky and irritable to him, and I find that he smells but no one else seems to smell him.
