What Is PdG?
PdG (Pregnanediol Glucuronide) is the urine metabolite of progesterone-the hormone that prepares your uterus for implantation and sustains early pregnancy. Think of it as progesterone's "footprint" leaving your body.
Why Test PdG?
1. Confirm Ovulation Happened
LH surges only signal your body intended to ovulate. PdG rise confirms ovulation actually occurred. Research shows PdG testing accurately confirms ovulation in up to 95% of cycles.
2. Check Luteal Phase Health
Progesterone transforms your uterine lining into a receptive "nest." Low PdG after ovulation may indicate luteal phase defect-making implantation difficult and increasing early miscarriage risk.
How to Test
Traditionally, PdG required lab visits. Now, home test strips let you track PdG easily. Best time? Test 7-10 days after ovulation (your implantation window), ideally with first morning urine.
Smart Tracking Tips
Look for trends, not single-day numbers-PdG pulses throughout the day
Pair with BBT charting for complete picture
Remember: PdG confirms ovulation quality, not sperm/fallopian factors
Whether you're in New York, London, or Singapore, PdG testing empowers you with one crucial answer: "My body is ready."
