cramps

I'm 10wk 1day and I've had cramps today..I've had cramps thru out the pregnancy but most of the time they stop..today seems pretty steady ..it's just making me nervous...I think it might have to do with not pooping right..but I'm so scared to miscarry..I've never had one and I'm so in love with this baby already..everything freaks me out :-/ ugh
