Yes it does this to me, when I am low on progesterone (i.e. increasing PM/estrogen without also increasing progesterone levels can lead to estrogen dominance symptoms).
The first 3 months of PM were ok and I grew over an inch (I was only using it 2 weeks on 2 weeks off), my nails grew strong, I felt fine. After that though I started getting very moody, pretty depressed, weight gain around the middle when I normally always stay the same and don't fluctuate, bloating, frequent headaches (normally never get them), libido plummeted, shedding a lot of hair, periods long and all over the place, and also my breast growth stunted.
A few months ago I started getting serious with the progesterone cream to try and balance it out. I used it for my luteal phase and used no PM. Then I used it for about a month straight and got my period the day I stopped it
I am a different person when I'm using the progesterone cream! So much happier, the extra weight dropped off my belly, my libido higher than in a looong time, no headaches, not shedding hair ect ect ect. I think I may be low in progesterone naturally due to various symptoms I've always had which disappear when I use the cream. One thing which was a surprise - all my life I have NEVER had any nipple sensitivity, and never had any swelling during my cycle or ever had sore boobs (no swelling or tenderness even during any of my 3 pregnancies). When upping my progesterone my nipples actually have sensitivity and it feels so good when hubby plays with them ect it really gets me going! This has never been the case ever. So it's a welcome change
I'm sure it will help my boobs grow too because I feel better about the and I feel sexier!
I've just started taking PM again for 2 weeks, tomorrow I start the progesterone cream for 2 weeks, and will continue to cycle to see if I get growth again
My nails have grown strong again for the first time since I first started PM a year ago so I think I'm on the right track. When I first took PM and got some growth (a year ago), I had been taking Maca for a few months prior - which I think helped balance hormones.
