I just found out i’m 5 weeks and some days pregnant

I’m 20 years old and this is my first time being pregnant! I want to know if very light cramping is okay? Literally I just found out yesterday and if i’m already 5 weeks, is cramping still normal they’re very very light! I woke up today so lightheaded and a bit dizzy as well but is that normal too? I had looked it up and a few sites said it is I just want to know what you ladies experienced at 5 weeks! Also breaths are slightly tingly to the touch but nothing major tbh. they aren’t dark yet or areolas aren’t “bigger/wider”
