Could it be to soon take pregnancy test if was only 2-3 weeks ago?

Yes, it is usually too soon to take a pregnancy test if it was only 2-3 weeks ago. Pregnancy tests work by detecting the presence of human chorionic gonadotropin (hCG) in the urine or blood. hCG is a hormone that is produced by the placenta after the fertilized egg implants in the uterus. It usually takes several days after implantation for hCG levels to become high enough to be detected by a pregnancy test. Most pregnancy tests are not sensitive enough to detect hCG levels until at least 10-14 days after ovulation. This means that if you took a pregnancy test 2-3 weeks ago, it is likely that the test result would be negative, even if you are actually pregnant.

If you are concerned that you may be pregnant, it is recommended that you wait until at least 10-14 days after ovulation or take a blood test which could be more sensitive to take a pregnancy test. You can also consult with your doctor or a pharmacist to determine the best time to take a pregnancy test.
