Hi, I found out I was pregnant December 4th 2014, and on 31st December I had some bleeding which was more brown in colour than red sorry if to much on information, I went to the early pregnant until where they scanned me and dated me at 5 weeks pregnant, but there was a empty gestational sac and a yolk sac no baby was seen, I was so worried as iv miscarried before but also had 2 successful pregnancys, they told me to go back for another scan when I'm 7 weeks to check if there is a baby and it's developed, I'm so nervous, has anyone ever had this problem before having a early scan and not being able to see a baby. With my last 2 pregnancys I had no bleeding and had every pregnancy symptom you can think of but this one all iv had is a little bit of cramps now and again nothing that I can't handle and feeling tired, should I worry about this pregnancy.
