How soon after sex can implantation occur?
Is it possible to get pregnant immediately after having unprotected sex?
Implantation is the process by which a fertilized ovum (egg) implants into the uterine wall to obtain oxygen and nutrients from the mother. This usually occurs between 6 and 8 days after conception. Conception itself can occur anywhere between a few hours and 5 days after intercourse. This is because sperm can live inside your uterus and fallopian tubes for up to 5 days. If during that period you ovulate (release and egg from your ovary), then the sperm can come into contact with the ovum to make an embryo. From this point on, the embryo must travel down the fallopian tube to implant in the uterus. This can take about a week. Only after implantation can you tell whether or not you are pregnant. This is because after implantation, the part of the embryo that becomes the placenta begins producing a hormone called beta HCG. This hormone is what is detected during a pregnancy test. Thus, you must wait about 2 weeks after sex to take a pregnancy test and know whether or not you are pregnant. I suggest that you schedule an appointment with your OBGYN. The two of you can discuss methods to increase your chances of getting pregnant (if pregnancy desired), or methods of birth control (if pregnancy not desired). In addition, you doctor can administer a pregnancy test. Good luck.
