No need to tell me to get a grip, you gave poor advice, simple as that. Obviously on a public forum it happens but hopefully the OP will be sensible enough to make the right decision.
In regards to the points you made- show me one pregnant woman who isn't concerned! Think it goes with the territory really doesn't it? Secondly, regardless of whatever system is in place, if everyone lied about being concerned, having spotting or pain etc then waiting lists would be huge and people in actual need wouldn't be seen promptly. The NHS simply doesn't have the resources to scan every woman in early pregnancy for reassurance and advising someone to abuse the system is in very poor taste if you ask me. Especially from someone who has been in actual need of it themselves!
