Should i test?

I started bleeding 4 days before AF was due. It was like dark brown and then bright red/orange. It only lasted like 3 1/2 -4 days. All this is really strange for me. Now it has stopped and I've been getting horrible headaches and kinda nauseous. My cervix is high ( almost cant find it) and hard and i think closed... CM is like watery with some white. Is this normal? I'm wondering about IB. Should I test?
