Morning, the leaflet does mention heavy bleeding so I was expecting that to possibly be a side effect for the first couple of months, its the clots that are concerning me. My periods have been erratic for the past year with bleeding being minimal some months and heavy others. My GP wants to run bloods, repeat my smear test and do an internal examination. The night sweats and hot flushes are horrendous and after trying holistic therapies and getting no where I opted for HRT.
