I’ve found I’ve got a really good history of being correct at guessing the sex based on the 12 week scan. Whether that’s from an educated guess or plain luck. Having had 4 myself I know how exciting/intriguing it can be, whether you plan on finding out or not...
So I’m going to start a thread for people who want to post their scans and I’ll give it my best shot.
OF COURSE - I am not an expert and this is just for fun 
I’d love it - as I’m sure other ladies will looking back - if you could update once you know!
