how long after implantation hcg
It takes at least 2-3 days after implantation for there to be enough HCG in your system to be detected by the most sensitive test available, First Response Early Result. If you do test and it's negative, don't fret, just wait a couple more days and test again with the First Response Early Result.Good luck!f you are pregnant, a urine pregnancy test is not expected to be positive until 3-4 days after implantation (at the very earliest), which is about 10 days after ovulation/fertilization and 4 days before the next period.
