This sounds simply miserable.
Have you talked to your doctor or nurse practitioner about this?
I was put on a HRT for non stop bleeding a couple years ago and had a similar response. I called the doctor after a couple of days and told her this wasn't going to fly and we had to find some other solution. I wasn't seeking a conception control but there are many options, I think it would be a good idea to look at other things you could use.
