17 weeks with so much stress!!

Is any one else stressed to the max? Like I can't feel the baby move yet and I have so much going on at home (pipe broke Friday and had no water and now no hot water) and my husband is a pain and kids are getting to me that I actually smoked a few cigarettes and now I am even more stressed that like the baby is not ok and my next appointment is April 21st and it's an ultra sound so I am worried there isn't going to be a heart beat.
