Cramping 5 weeks...

Sakecat • Hi! 2nd baby. Im 29. I already have an 8yr old boy! Although life has changed a lot; I'm just as excited & worried!
This pregnancy is so different than my first.  Unless I forgot - it has been 9 years!! But I don't recall having much nausea....(And at night!!!)
Anyways, my concern is I've been camping... Maybe I was spoiled my 1st pregnancy- I had no issues or discomforts. ... Just a belly and heartburn.. Nothing tums or sweatpants couldn't fix. .. The cramps scare me.  There's no bleeding. And they're not severe. Reminds me of period cramps... Any similarities !? Anyone else experience this ? Should i worry ?
