Riss you were so like me. Just think at this point in time you are more pregnant than not. No spotting is a great sign. Have the bt done but I would think twice about an early scan. I waited till 7 weeks as I wanted to make sure if there was a heart beat to be heard I wanted to hear it. I couldnt bear the thought of them saying it may be too early come back in 2 weeks. I nearly had and anxiety/pannic attack just before the scan and walking out if there without a heartbeat was not an option. There was no way I was going through that twice. If it will make you feel better then go for it but be prepared for them to maybe not hear the heart beat. Try relax, you are more pregnant than than not so please try to enjoy it.
