Having sex without birth control and not getting pregnant means you got lucky. You may get lucky multiple times, but this does not mean you are infertile. It means you are pushing your luck: 95% of young couples who have sex once a week are pregnant within a year. Most of us have heard that ‘it only takes one time.’ While that’s true, there are a lot of factors involved, and most couples who are actively trying to get pregnant get there within 6 months.
By 2007, scientific consensus was building that morning-after pills did not block implantation. In one study using fertilized eggs that would have been discarded from fertility clinics, Dr. Gemzell-Danielsson found that adding Plan B in a dish did not prevent them from attaching to cells that line the uterus.
Later, in 2007, 2009 and 2010, researchers in Australia and Chile gave Plan B to women after determining with hormone tests which women had ovulated and which had not.
None who took the drug before ovulation became pregnant, underscoring how Plan B delays ovulation. Women who had ovulated became pregnant at the same rate as if they had taken no drug at all. In those cases, there were no difficulties with implantation, said one of the researchers, Gabriela Noé, at the Instituto Chileno de Medicina Reproductiva in Santiago. Dr. Blithe of the N.I.H., said, ‘No one can say that it works to inhibit implantation based on these data.’
Can you tell if someone has an STI just by looking?
