Congratultions!!
Your GP might not confirm it, mine didn't! he just refered me on to a Midwife who saw me for 5mins at 8 weeks (I think) to get my notes started, and then at 10 weeks for a 'booking appointment' where she took a complete history and arranged my first scan - usually at 12 weeks, this is to confirm that you are pregnant, how far along you are, that the embryo is viable and in the right place.
I hope you have a very healthy and happy pregnancy! Take care. x
