Feeling off

Hi!

So I’ve been feeling really off these past couple of days. I’ve had a migraine for two days straight and a pain in my clavicle area for three. Today I went to use the bathroom this morning and went #2 and there was blood in it. I’m also really fatigued and my last period was in April. I’m not sexually active so the chance of a pregnancy is 0%. Is this just a weird reaction to my period coming or something more serious?
