Totally unexpected bfp at w/e as it took well over 2 yrs to conceive dd (who is now 13 mths). I was hyper-cautious over all sorts of things last time but now can't remember what. Can anyone remind me of anything I should think about e.g. I jumped in a lovely hot bath on the w/e and dh pointed out that he was sure I didn't do that when last pg. Also, when am I supposed to contact the doctor to get in the system for scans etc?
