I definitely wanted to know and DH didn't, so we agreed that I could find out but not tell anyone else except my mum, and I wasn't to tell DH that I knew. So, before our 20 week scan I slipped the receptionist a note explaining the situation, and asking that the sonographer write down in his notes what the sex was. I then called back later and found out.

I'll definitely be doing the same next time. I managed to keep the secret throughout the pregnant, and just hid the girl flavoured things I bought along the way from DH. I loved knowing we were having a little girl (and so did my Mum!!) and DH and I were both happy.
