FPA Contraception

Marvelon contraceptive pill issue

I was previously on Microgynon for 6 months and experienced spotting throughout the course of my pill, so the doctor put me on Marvelon and since I started my strip I’ve had non stop random breakthrough bleeding that varies in heaviness. I’m just looking for advice and want to know if anyone else had has similar problems with it as I cannot find any information anywhere. Thanks :)
