When Does Implantation Happen?
[Medical content to be added — typical timing 6–12 DPO, implantation range, what happens at the cellular level.]
How Long After Implantation Does hCG Rise?
[Medical content to be added — hCG doubling time (every 48–72 hours), minimum detectable levels for home tests vs. blood tests, timeline from implantation to detectable hCG.]
The Earliest You Can Take a Pregnancy Test
[Medical content to be added — home urine test sensitivity (10–25 mIU/mL), blood beta-hCG (can detect earlier), earliest reliable day (14 days post ovulation/IUI, 14 days post 5-day transfer).]
Why Early Testing Often Gives False Negatives
[Medical content to be added — hCG not yet at detectable level, test sensitivity variation, IVF progesterone impact.]
