Hi. I Recently Began An Increase Of Lisinopril From 10

Hi. I recently began an increase of lisinopril from 10 mgs. to 20 mgs. My doctor suggested this and to stop taking my amlodipine so that I would just be on one drug. Immediately after I began taking the increased dose I began having vaginal bleeding for approx. 15 days now. I stopped the lisinopril all together and I am waiting for the bleeding to stop. How long will it take to stop? Will it stop? I plan to call my doc tomorrow but I'm just curious as I stopped on Friday and this is a long weekend and I'm still bleeding. Thanks.
