Hi Maria,
I know my situation's different, (2 pumps Esgtrogel and 1 x Utrogestan in the eve days 1-25) and I've had that discomfort/pain in my chest for a while, but noticed the last few days it had started to dissipate, and I just realised that's because I was on my progesterone break, I had spoken to the docs about it and as Ive only been on it a month she said to let it settled but could well be the Utrogestan causing it. I'm due for a coil fitting in a few weeks and hoping that helps.
She did prescribe me buspirone to take if it gets really bad. I haven't taken it yet, don't want to rely on them, have you heard of that?
Though I guess it sounds like it's Estrogen for you.
Not helpful I know but just wanted to say I sympathise, as mine has been awful recently, I'm also very very teary, something I never used to be.
Sending hugs x
