If ovulation was on 17th April when is the earliest you can test for pregnancy?

If ovulation occurred on April 17th, the earliest you can test for pregnancy is 11 days after ovulation, which would be April 28th. This is because it takes about 11 days for a fertilized egg to travel from the fallopian tubes to the uterus and implant in the uterine lining. Once the egg has implanted, it begins to produce the hormone human chorionic gonadotropin (hCG), which is what pregnancy tests detect. However, it's important to note that some pregnancy tests may be more sensitive than others, so you may want to wait a few more days for a more accurate result.
