Pregnancy Info HOME

This is my fourth pregnancy and my pre pregnancy weight is 96 lbs I have had no complications with any of my pregnancies, I also have always lost a few lbs in the first trimester, I have never had many symptoms just kinda smooth sailed through the whole thing. This time I went to my first visit and he could not find a heart beat and he did an ultrasound and found the baby and the heart then found another sac a little bigger than the first but could not see if there was anything in it, he said either it was a twin but not anymore or it still is but he can't see it, he said it looked like I was around 8 weeks along. I have gained 8 lbs and have had 24/7 sickness and I am more tired than I thought a person could ever be, I can also feel my uterus half way up to my belly button. My next doc visit will be march 6th and he said we will do another u/s around 18 weeks. What do you guys think about all this? has anyone had this happen? mostly i'm just driving myself nuts about this not knowing. Any advice will help:-) thank you
