Hey congrats on your fab newx, fx all is ok this time.
I know how you feel when you are anxious, i have had a mc and ectopic before having my daughter FEB 09, and i got my bfp in NOVEMBER. I have had 2 scans now and got my dating scan on the 12th Jan. My 1st scan at 6 weeks only showed pregnancy sac and yolk sac, and my scan at 9 weeks showed baby and hb. I was really shocked as i have had no symptoms this time round whereas i was so sick and ached, tired sore bb with my daughter so i was expecting to have imagined the whole thing!!
Really hope all is good for you this time round xx
