Anyone here with a short luteal phase that can offer me insight???

Anyone else have a short luteal phase, and how long have you known or been seeing a doctor treatment and/or education about it? I hear it can be caused by MANY factors, what have you found out may be causing yours?

I’m 37, I’m trying for baby #1, I’ve been TTC for only two months. I chart with bbt, OPKs and CM.

I only starting charting in the last 2 months and last month I was right on the cutoff line: 10 day luteal phase. I know abnormal luteal phases are categorized as less that 10 days. Under 10 is usually a sign of infertility and requires treatment with you doc. Well… this cycle it was only 7 days. 😳🥺 I know it’s hard to know for sure that it’s not just a fluke month until next my cycle or several cycles more, but I want to educate myself as I’m concerned! I’ve never tried to get pregnant before so my baseline for what is normal for me is not great since over never before the last two months thought about or even knew about my luteal phase at!

Help friends! I just want more insight please share your experiences with me! 🙏🏻❤️🙏🏻❤️
