Are you on anything else? Just wondering why only the Utrogestan? That’s progesterone. Are you on any Estrogen?
Usual regime with peri is to have Estrogen, but unopposed Estrogen isn’t good for womb health so for (usually) 14 days, progesterone is added alongside the Estrogen to encourage a bleed, to keep the womb lining healthy.
When I was peri, I started with Evorel Sequi. An Estrogen patch twice a week for 2 weeks, then a combined patch of Estrogen and progesterone for the next 2 weeks.
