Cervix like a rock!

Hey all, I am around 8dpo roughly, I've got absolutely dreadful cramps, thought my period was coming and for some reason felt the need to check my cervix, which ended up feeling like a rock, high and closed. I mean it's completely like a rock, in the 11 months ttc it has NEVER felt this hard!! 
Really hoping this is a sign but probably not and I know it's too early to get a bfp even if I am pregnant. I think I just want this so bad and looking for any sign! 
Is it normal for it to be that hard though, especially if it's never been anywhere near that hard?
TIA
