Hi Tc
I wrote a really long reply, but it seems to have disappeared before I could post it!
I’m just wanting to describe the Oe, P and T and SBHG connection....
Progesterone (natural and the progestin Norethisterone) have low binding affinity with SBHG.
Oestrogen has high binding affinity.
Testosterone has the highest binding affinity.
So it’s probably not that you’re not absorbing the Oe, but that it’s binding with the SBHG and not leaving enough free (useful) Oe to be used by your body.
I started using T in mid December last year (I’d ditched the P two weeks earlier because I was just fed up). So after those two weeks of Oe only, I added the T (Androfeme 1%, .5ml on outer thigh daily). It took about two weeks for that anxious, gnawing, horror anxiety to quieten. I still had it, but much reduced compared to how it had been. My self confidence improved too. After four full weeks of no P, I then re introduced P (Utrogestan 100mg) vaginally for seven days. This was much better, although erratic bleeding continued to be a problem (as well as symptoms during P week). I had a Mirena inserted on 3rd of this month. And I’ve not felt so hormonally stable in about 25 years, since my late 20s (taking Diane 35, an ocp with oestrodial and cyproterone).
I researched it beforehand as I’d discussed potential side effects, etc with the gynae. Apparently Levonorgestrel (the progestin in Mirena) has almost as high a binding affinity for SHBG as T, which is possibly why so many ladies get on with it. (I’m very aware that many don’t, too, but I decided to try it first, before dismissing it out of hand). It can take 3 - 6 months to completely settle so I’m not cracking the champers just yet.
So give the T a try. I put mine on in the morning, and before I change my patch. I’m on 100mcg like you - and I’ve also found that changing it in the morning, every third day is better (rather than 3.5 days) as symptoms would be returning on the afternoon of that third day. I just have to remember what day I’m up to lol.
As for the Utrogestan - perhaps give it a break for a couple of weeks whilst you’re introducing the T. You’ll likely get the P withdrawal and a bleed for the first week or so. Then once your serum levels of T are up (you should be able to feel it after about 10 days to 2 weeks) you can always reintroduce it vaginally like so many of the other ladies on here use it. I personally found vaginally was a better option symptom wise.
Good luck with it all xx
