Early scan

Laura • Hello. I'm 21 I have a 14 month old little boy and I have just found out me and my partner are expecting our second :)
Hello I went for an early scan today and estimated 5+ weeks, she said there is a yolk and sac but there is also a large area of bleeding outside the sac, I have to go back for a rescan in 2 weeks time, should I be worried :/ ..
I had a previous ectopic and she said it is in the correct place in just bleeding in the uterus :/
