I wish I could help you, but I have no idea. I would call a pharmacist and start by asking him. Then I would call her GYN doctor and ask him or her. I am sure that they can give you the answer you need. Good luck, slc
about 2 weeks after intercourse a pregnancy test can be used to determine if she is pregnant, but that is about the time a menstrual cycle would be late. It might be a good idea for you to find out how babies are made it can help a ton when trying to conceive. about two weeks after a woman has a period, she becomes fertile by releasing an egg to be fertilized. if sperm fertilizes the egg it takes a journey to the uterus that take about two weeks then implants into the uterus, the female then starts to produce the hormone HCG. HCG is the hormone that turns pregnancy tests positive. because it takes two more weeks for the egg to travel the whole time ends up being equal to the same time a period would be due! Good luck, hope this helped a little bit.
