Can add back cause bleeding when on prostap?

[Fortyoneandcounting]

On my third month of prostap and started add back (livial) about two weeks ago, started bleeding and lots of lower back pain? Could this be from the add back?

Hi there.I was on Prostap for 10 months with Livial/Tibolone add-back from the beginning. I tended to have a couple of weeks bleeding (1 week on, 1 week off) for the first couple of months, then it went down to a week each month. It finally all stopped at around 7 months. But it was more like brown discharge at the end of a period and not very heavy.

I had my endo back/leg pain throughout so can't comment on your back pain.
