When should you worry when cramping?

So I’m one of the unlucky ladies that is very nauseous and who isn’t spared at all by morning sickness yay. I’ve gotten used to the nausea but right now something else happened… so I’m 6 weeks and this hasn’t happened before but I’m cramping. It’s nothing serious I wouldn’t say menstruation kind of cramps it’s…. Weird. Like a bit less severe than menstruation cramps followed by a strange stretching or pulling feeling? I just want to make sure that’s normal.. Because I’m not gonna lie I’m a bit worried.. then again I freak out at every new symptom so 😅

The cramping seems to be like on and off? Like it’s there it hurts but then they’re much lighter and now it seems to be going away… any reassurance please?
