“Why am I not pregnant yet?” This is the heartbreaking question so many women ask when they’ve done all the work: the detailed tracking, the perfect timing, the healthy habits. If you feel like you’ve mastered the first half of the process, it’s time to dig deeper. Sometimes, the missing piece isn’t your tracking skills—it’s your hormone balance.
A progesterone deficiency can silently sabotage your cycle and prevent a pregnancy. To help you get answers, we’ve listed some of the major progesterone deficiency symptoms to look out for. Listen closely to your body’s signals below!
6 Key Signs of Progesterone Deficiency to Watch For:
- A Short Luteal Phase: The time between ovulation and your period is too short.
- Luteal Phase Insomnia: Waking up or trouble staying asleep after ovulation.
- Hot Flashes or Night Sweats: Your hormones may be confusing your body.
- Spotting or Light Bleeding Before Your Period: Progesterone helps stabilize the uterine lining, so early spotting can indicate the lining is breaking down prematurely.
- Low Blood Sugar: Progesterone is crucial for maintaining stable blood sugar.
- Low Libido: Low estrogen levels, which often accompany low progesterone, can impact sex drive.
