<human>: I have really bad back pain , severe headaches, im always exhausted I get bad cramps almost everyday and i have been spotting almost everyday for the last 3 weeks. I just wanted to know if it is because of my birth control. It only started when i started my birth control pill for the first time.
<bot>: Side effect of oral contraceptive pill (OCP) is headache, back pain, weight gain and thromboembolic manifestation. Cramps in calf muscle is not a good sign. You may be prone to deep vein thrombosis. I would suggest you to get a gynecologist opinion and tell her that you are having cramps every day. May be she'll shift you from OCP to any other contraceptive method like intrauterine contraceptive device (IUD)
