Hi,
I had Mirena fitted approx 6 weeks ago. I need to take utrogestan as well to get the systemic progesterone my body craves. The Mirena is to control the bleeding and help my fibroids etc, but as it’s so localised, I take utrogestan daily too. I know it’s early days for you, but it is quite common for have both Mirena and utrogestan (or other progesterones) together.
I didn’t sleep as well with just the Mirena, sleep is back to normal with added utrogestan.
Also had biopsies at the same time as Mirena fitting. Results came back 5 weeks later and they were fine. I have my fingers crossed yours will be too.
