Normal bleeding?

Any one know wether this is normal or not? Is it period? I have no blood flow but been dealing with this for the last week only today it is dark brown but it’s been ranging from clear to bright red and now this. I’ve been on the pill since my last girl came off 2 months ago so dunno what to expect with periods. I also did take a plan B last month; & have had a lot of unprotected sex since.. pls help; getting cramping to in one side of my rib and stomach twinges aswell as random body aches.
