Pregnant?

Hey ladies. So my cycle is normally anywhere between 26-29 days, I’m now day 32 and still no AF. I’ve been cramping the past few days and had sore boobs like I’m going to start, but still no sign. Now today I feel faint, almost like my blood pressure is low and I can’t concentrate. Am I just over thinking? I know I should test but I’ve wasted so much money on tests in the past 🤦🏻‍♀️
