Way to tell the OH? Do I wait?

[RachelLynda]

I've literally just found out I'm pregnant.. Me and my other half are going away for our birthdays this weekend (7th is his 8th is mine) I really want to tell him but i want to wait until his birthday to make it extra special. I'm still only 9(?) dpo and it's a clear and visible line but not a smack you in the face line.. It definitely will be by the Saturday. But as we're going to thorpe Park Fri-Sat I kinda want to tell him on the Friday so he'll know why I'm complaining I feel sick all the time and won't call me a baby because hell think it's the rides haha (he'll only be joking!)
I'm in two minds.
One wants to tell him the moment he's home and the other wants to wait until his birthday.
