Currently 6 weeks pregnant (4 weeks since conception) but many things (previous miscarriage, taking a very long time to conceive, no pregnancy symptoms etc) have me convinced (read: completely paranoid) that I am not pregnant/have already miscarried despite BFP. I want to have a private scan as soon as possible to (hopefully) prove me wrong but what is the earliest I can have it done? I don't even want to start the NHS process before I have seen a heartbeat as can't take another round of appointments if it's all for nothing like last time.
