I was on kavira 7 months when I began to expreience break though bleeding - then no bleeding then getting my period one week early and bleeding for a 10 days. I also began to experiece anixety, night sweats and restlessness. Basically "change" symptoms. They have recently switched me to Ovcon and I am still having these sy,ptoms. Has anyone else expeienced this I am 38 anf began to take the pill to control migrains and heavy bleeding. I am ready to get off and reg my hormones!
