I received one Kenalog 10mg injection on 12/28/2017 for rashes/hives due to antibiotic allergy. my period has been very regular 28days for the past 10 years. after the kenalog injection, my period came 3 days early which I think it’s alright but they are heavy , bright red and I am worry. It’s been going for 2 days now. No cramping and no pain. I am wondering if this is related to the kenalog injection ? Now I hope my bleeding will slow down. My doctor said it’s not related... which I don’t believe what she said. Please help
