Cramping...should I go see a Dr?

Brittney • I`m 32 years old and have a almost 2 year old son (bday 9/3) and pregnant with our little girl (due 10/4)
I'm 25+3 and for the first time I have almost period like cramps, mild, intermittent but there. I have had a SUPER easy pregnancy, some Braxton hicks...but this is more like that period/diarrhea kind. My son is still kicking away and I'm not bleeding or anything. Should I call or go see a doctor? If so when? This is my first pregnancy, maybe this is normal? Maybe I ate too much cheese?! LOL 😅
