Is this Birth control making me worse? I feel pregnant!?

I need opinions, I don't know if i should get a hysterectomy or keep going with the pill. I had my tubes tied in o7 and also had a endomentrial ablation in oct of o8 to ease heavy bleeding. I didn't have any periods until july of this year, then they just wouldn't stop it was very light until Sept were it was starting to get very heavy again. The doctor put me on mircoestin 21 until she could get me into a appointment. I have headaches and feel completely pregnant, peeing all the time hot flashes and im cranky! are these all side effects of the pill? i couldn't possibly be pregnant. Im sick of my body being messed up hormonally. Should I just get the hysterectomy
