had a miscarriage at 5+4 :(

Sadly I had a failed pregnancy at 5+4 it has now been 3 weeks since it happened but it hasn't really hit me till the past few days I've got a 3yr lg so she's kind of kept me busy I didn't want to be upset round her but I feel like I've left it too long to talk to my partner about it :( I don't really want to bring it up and up set him all over again but then it's recking my head not talking about it. I just want to kick, scream, cry and be cuddled in his arms, should I talk to him about it or have I left it to long? I just didn't feel ready to talk straight away.
