Question: how long does it take for your hcg levels to rise after implantation?
Answer: How does implantation affect hCG? Implantation occurs on average, 9 days after ovulation (with a range of 6-12 days) or about 5 days before a missed period. hCG levels are detected in the blood as early as 2-3 days, and in the urine 3-4 days, after implantation.
