@Chillout71 sounds ok to me? Did the nurses say it's ok? From what I've read hcg can double over 48-72 hours so over 5 days for it to go up from 1600 to 6000 sounds on track? When is your scan? Mine is in a week and it can't come quickly enough! I don't really have any symptoms other than sore bloods and occasionally feeling a little queasy. A bit freaked out by my lack of symptoms!!
