Does Micronor Cause Heavy Bleeding?

I have been on Micronor for 2 1/2 months since my doctor took me off Ovcon 35 due to High blood Pressure. I have been bleeding heavily for 3 weeks now. I used to work for a gynecologist and trust me, I know when bleeding is not normal. I have been bed ridden for the last 2 days. If I get up there is so much pressure and blood that I am constant ly in the bathroom. Is this nomral on Micronor?
