Cramping pains , heavy tummy ?

I know I'm only early approx 9/10 weeks but I've been having cramps and strange feelings in my lower tummy today. Sounds crazy but it feels like there's something heavy down there and my tummy feels like someone's moving there hands around in side it , I keep going to the toilet every half hour just constantly wiping myself checking as I'm panicking it could be the start of a misscarriage. I've had previous misscarriage but these pains and feelings are nothin like that. Surely I can't feel baby moving so early?
