Hi Suzziep
Postmeno women with a uterus are usually started on continuous combined hormone therapy, which means both the estrogen and progestogen (Utro in your case) are taken on a daily basis. No break. For many women, this approach leads to no bleeding.
Edited my post to add that breakthrough bleeding may occur in the first 6 months of a combined MHT regimen. Any unscheduled bleeding after that should be investigated.
