I'm going to do an update post, since I've found it useful looking back over my own posts from last year.
So, I stopped both the progesterone and bio clear oestro due to the extreme reflux /gastritis. That's still ongoing.

Since stopping. I had an OK week or so through Xmas (thank god) but then last week I descended into horrific pms. Like truely horrific. Mood swngs, extreme emotion, daily migraines and an inability to deal with life, never mind stresses. It was awful. So I was very grateful for my period to arrive after only 21 days.
I used ovulation strips last month. No ovulation. Which corresponds to low prog and pms and short luteal phase.
Roll on my period I thought. But no. Now day 3 of my cycle and I am back to square 1. I feel dire. My extreme estrogenic symptoms - this time with no prog to help, as last month was annovulatory. Motion sickness and nausea and grumpy. Looking back these were all things I suffered from in follicular from day 2 originally and then they increased in severity when I began prog..
So. I can conclude that adding progesterone definitely improved my mood, pms and migraines, but for me it did increase my estrogen causing further imbalance in follicular phase.
So now I'm back at the start. I'm on day 19 of agnus castus. It's not doing anything as yet, but it's a slow acting herb. I'm so praying that it helps me ovulate and start making a decent dose of my own prog. I'm still damn sure that's all I need.
Its going to be a long week...
