Anyone not finding out the sex?

So we have our next scan on 11th April and were thinking about not finding out the sex. It's so tempting to find out the sex when your there I know! But this is such a special baby to us. We tried for 8 years and had 3 mc's. We really don't mind what we have either, we have a 9yr old girl already.  I just think the surprise would be amazing as there's not many surprises left in life these days.
