11 weeks and symptoms return with a vengence

I am 11 weeks today and for the past week or so I've been feeling a little better, still tired but better. Today I woke up exhausted, moody and so sick. Got into an argument with my husband because I couldn't find my socks and I felt like it took every once of energy I had to find them. I feel a lot of pressure in my stomach but no cramping. Probably my uterus stretching but awfully uncomfortable. Anyone else experience this? I thought I was past the worst! I could just cry!
