.................and I promise to make this my last for the week, but have just been chatting with my mum about my midwifes appointment, Im about 5+4 and im booked in in two and a half weeks, my mums just asked how I know that date, which basically ive got off a clear blue digital thingy and a bit of guestimation because I cant remember the date of my last period, anyway she has all but insisted that I need to go to the doctors because she thinks im further gone, however I had a negative last week, and clearblue saying 2-3 weeks, is it possible that im further along and didnt know it? has anyone else had this experience?
