So I'm a few weeks into taking HRT. I'm on Oestrodose gel and Utrogestan. I started the Utrogestan on the 1st of month and was expecting to bleed when I stopped after 12 days. But I started bleeding today (after 7 days of Utrogestan). My period has basically come at the time it was roughly due. Is that normal? Will it take a few months for things to find a rhythm?
