Added complication symptoms and conditions

I had a kenalog injection in my shoulder at the end of October during my period, my next period was 4 days late and appeared to be normal, 18 days later I started bleeding again which went on for 13 days, I had 5 days off and am now bleeding yet again. I have an added complication of being on warfarin for life for recurrent PEs so Drs are unable to give me anything to stop the bleeding. I was referred for a pelvic scan and am now waiting to see a gynaecologist. No medics seem willing to admit kenalog may be the cause. As my blood has to be kept thinner & I bleed easily, I am very concerned at the amount of blood I am losing. When I had the initial jab the consultant did warn me I may have menstrual irregularities which I interpreted to be a few days early or late, certainly not non-stop bleeding.
I couldn't believe what I was reading when I found this site, so many of us are suffering, why weren't we warned of the side effects. I certainly wouldn't have had the first injection if I had known and I will not have any further ones.
