I have my 20 week scan on Thursday and I'm just so excited I could burst. It's all I can think about and I've been counting down the days for 3 weeks (which actually made it go slower lol). I can't sleep, I can't conccentrate at work, I can't wait to see my baby and find out the sex and make sure he/she is ok etc. Is anyone else as excited as this or am I OTT about it all??!!
