Cramps!!

Hi everyone!! Wondered if anyone could put my mind at rest! 
I'm almost 6 weeks and very excited!! However since I've found out I've had consistent cramps! They feel like period pains really ! There not overally painful but sometimes can be quite sharp!
I've read it's your uterus stretching ect. 
I just wondered if anyone else had had these symptoms? 
Thanks for your helps!! 💜💜💜💜
