Iatrogenic POI and TTC with HRT - right protocol?
Hi everyone,
I'm looking for advice and especially to hear from women with POI who were still able to conceive with the help of a fertility clinic/HRT.
I have iatrogenic POI. After my cancer treatment, I was fortunate enough to have a child, and we've been trying to conceive again more or less since 2023.
After getting COVID in early 2024, my periods stopped completely. Since summer 2024 my FSH has mostly been around 100, and the fertility clinics I consulted basically considered me a hopeless case.
A lot has happened in my life since then, but a few months ago we decided to contact clinics again for one final attempt (In fact, at that time I suddenly had two days of spotting without being on HRT or any other medication).
Of the two clinics that were willing to give us a chance, we chose the one that had clearly taken the time to thoroughly review my medical records and gave us the better overall feeling.
However, they're not particularly optimistic and also fairly conservative in their approach. For example, they don't prescribe DHEA because they don't feel the current evidence is strong enough.
Since my estrogen levels were barely detectable and the goal was also to bring my FSH down, we started transdermal Oestrogel (1.5 mg estradiol daily). At my first follow-up one week later, my endometrial lining measured 4–5 mm, which was encouraging. However, another week later it had decreased to only 2–3 mm (This was explained by the fact that I'd applied the Oestrogel to my thigh instead of my upper arm that week, had come down with a cold, and had taken ibuprofen).
As there was still no visible follicle, I started vaginal Utrogestan/progesterone 200mg for 10 days on cycle day 16 anyway. On cd 31 and 32, I had some dark brown spotting, but according to my clinic this wasn't considered a true withdrawal bleed.
An ultrasound on cd 34 showed that my lining had increased to 7–8 mm, and the clinic assumed that the withdrawal bleed would still happen. My estradiol (E2) level at that point was 788 pmol/L.
Now it's cycle day 40, and the bleed still hasn't started. I have another follow-up appointment tomorrow.
I've continued using Oestrogel every day throughout. There were no ultrasound scans while I was taking progesterone, and at no point were my FSH or progesterone levels checked again.
Has anyone experienced not having a withdrawal bleed despite taking progesterone?
Which treatment protocols ultimately led to a successful pregnancy for you?
Is there anything in particular I should be paying attention to or asking my clinic about?
Over the past three years, I've spent countless hours reading, researching, and trying to learn as much as I can. I'm so grateful to everyone who shares their experiences in forums like this—it really does help.
I'm now 41, and we've decided to give ourselves until the end of this year before accepting that it's time to let go of our dream...
