Hello!
I've found it helpful to read about your journeys, so I thought I'd share mine. I'm 57, postmeno, began combined continuous HRT in 2020, under the care of a meno specialist. I started taking Estradot 50 and oral Prometrium/Utro 100 mg. I experienced breakthrough bleeding, which is not uncommon when starting continuous combined HRT, but my bleeding persisted. Transvaginal ultrasound, sonohysterogram, endometrial biopsy were negative of findings. I had a thin endometrial echo of 1 mm. I had read that an endometrial thickness of 4 mm or less has a greater than 99% negative predictive value for endometrial cancer, so I've tried not to worry about being in the 1%. Unscheduled bleeding is so stressful. My doctor wanted to reduce my estrogen to address the bleeding, but I asked him to keep me at my current dose for a little longer. We waited and hoped the bleeding would stop. It didn't. We talked about the Mirena IUD as a future option to control the bleeding.
At the end of April 2021, I tried switching the progesterone from oral to vaginal admin which triggered a bleed, and then I had another bleed two weeks later. My doctor thought the increased frequency of bleeding was likely due to the switch and asked me to monitor it. I switched back to oral due to the increase in bleeds. The bleeding became more erratic. All my meno symptoms returned with a fury. They were worse than before I'd started HRT. And then there was the sudden hair loss.
The hair loss was readily apparent to my doctor and he suspected low estrogen. He ordered blood tests for thyroid (TSH) and estradiol. My thyroid was normal, but my estradiol level was <40. I'm at the bottom of the scale. Confirmation that I'm not absorbing transdermal estrogen. And it may explain the bleeding. Progesterone breakthrough bleeding occurs when the progesterone-to-estrogen ratio is high. The endometrium can become atrophic and ulcerated due to a lack of estrogen and prone to frequent, irregular bleeding.
This morning, he prescribed an oral estrogen, Premarin 1.25, and Prometrium 200 mg. His preferred oral estrogen is Estrace (estradiol) but it's on backorder. The plan is to switch me to Estrace when it becomes available. My pharmacy has ordered the Premarin and it should be available next week. A new hormone adventure awaits.
My GP has referred me to a dermatologist for the hair loss and told me to start using minoxidil (Rogaine/Regaine) while waiting for my derm appointment, which could be months away, to preserve the hair that remains. And so my minoxidil journey begins. I've used it for the past two days. There are potential side effects. I'm going to hope for the best and not dwell on them.
If anyone has any good things to say about Premarin, minoxidil or hair loss treatments in general, I'd love to hear it. I was really hoping that transdermal estrogen would work for me, but I can accept the increased risk of oral estrogen. It's got to be better than this. It's such a relief to have confirmation that I'm not absorbing the patch and be able to move forward. It's unfortunate it took so long to get here.
