I went to the ER because I was bleeding right after I found out I was pregnant and I have lost 7 pounds they did an ultrasound and they told me I was only 5 weeks and then everything was okay I went again when I was 9 weeks for losing 20 pounds and can't keep anything down and I had HG but they said that with how high my HCG was it's rare to have an single pregnancies is it possible the first ultrasound missed something? Have my 11 week ultrasound tomorrow.
