smokeandglitter - I am experiencing the same symptoms as you, the cold symptoms, blocked nose, constant sneezing, sinus headache etc had it since the very beginning and am now 17w 3d.
Also, for anyone not on the fb page, I have a wee update! Last weekend at exactly 16w we went for a gender scan and got told we were having a boy, but to come back the week after for confirmation as they werent as sure as they normally are. They told us 80% sure. So we thought 80% was high and surely this wasnt wrong. Cue us going out and buying a few wee blue things and picking 3 boy names.
But yup, it was wrong! Went back on Saturday there and we are now having a baby girl! 99% this time, said they couldnt be more sure, and she is defo a girl!!!
My OH is in shock haha! I think I was kidding myself on I wanted a boy, because I am overjoyed at the thought of having a girl!!
Back to the drawing board on names now, although we like Leana or Iona.
