Progesterone During Luteal Phase Only

by Marie

I am 44 and trying to conceive. My cycles are like clock work. I chart with temping, so I know I'm ovulating each month. I began using 100mg/day of natural progesterone cream beginning at ovulation several months ago. I've heard others take it all month long. Is there more that I should be doing? I had two miscarriages over a year ago, and haven't conceived since. I've read many articles on here, but can't find a concrete answer for my situation.

Maybe I'm being impatient, and I know it takes longer in your 40s, but I'd appreciate any advice....especially if I should be using the cream all month long.

Progesterone during Luteal Phase only

Hi Marie

When first using progesterone it should be used every day for 2-6 months in order for the body to adjust and to eliminate estrogen dominance symptoms. Once the body adjusts and the monthly cycle returns to normal it can be used by following the cycle especially if you are trying to conceive. If you are happy that you are ovulating with regular monthly periods, then I suggest that you use progesterone cream by following your cycle. It should only be used from ovulation (Luteal Phase) for the last 14 days of the cycle. The Pregnancy page will explain in more detail.

What is your Vitamin D3 level? A deficiency reduces the benefits of progesterone. Co-factors are needed when taking D3, namely Magnesium and Vitamin K2 with NO soy.

Thank you so much for your advice. Yes, back in January, I did find out my D3 was low, so immediately worked to get that up. It's fine now, and I continue to take D3 supplements. My magnesium was good, and I'm not sure about K2, though I suspect it is fine considering I eat a lot of cheese, butter, eggs, beef, and chicken.

I've read the articles you recommended, and it seems I just have to wait it out. Since my cycles are regular, I don't want to disturb anything, so I'll continue to use the cream in my luteal phase as I'm already doing.

Thank you again for taking the time to respond.
