having consistent cramps, is that ok?

Clau • CGR
I'm suppose to be 4 weeks pregnant( I think i have just 3 weeks) I just wanna make sure that cramping is ok. I'm been cramping consistently for the last 2 weeks , not so heavy or painful but since Thursday I have one big cramp here or there.(level 7-8 in pain) Maybe I have had 4 since then. First baby. Just let me know if it's normal. 
Thanks girls 😊
