3rd pregnancy, 10 weeks, unplanned. Horrible sickness - mostly just crippling nausea, but I just threw up in the kitchen sink as couldnt make it to bathroom on time! 
I am spending my days on the sofa /in bed, and my 2 preschoolers are watching hours of telly. I am doing pretty much nothing round the house. I feel exhausted, sick, emotional and depressed. I had pnd after my 2nd child, and now I'm worried - is feeling so down just a natural thing because I feel so I'll, or is it depression.
