My girlfriend last period started on the 31st of May. On the 14th of June, we had sex, and the condom broke, but I didn't come. I changed the condom and this time I pulled out and come on the condom. After an hour, i bought Plan b and gave it to her. She felt dizzy after 3 hours of taking it and the next day too, but now she is okay. What are the chances of getting pregnant?
According to the Manufacturer, Plan B will not work if your gf was already ovulating. It was still worth taking it, to give you a chance of not conceiving.
The time you had the accident was right on the time that most women would be ovulating, so it may not be on time to delay the ovulation.
There is a definite chance of pregnancy from pre-ejaculate/pre-cum. A study from Human Fertility showed that men who have sperm in their pre-ejaculate, always have it in there, whether or not they urinated since their last ejaculation.
Some people have thought that Plan B might work in additional ways to prevent pregnancy, such as making the lining of the womb unsuitable for implantation, & preventing the sperm meeting the egg, but the Manufacturer does not state any of those as ways Plan B works. They say it only works by delaying ovulation. If it's too late to do that, then you therefore may not be covered against pregnancy.
In this situation, I would have advised looking into getting a coil/IUD fitted by a doctor within 5 days of the accident, in order to try to prevent pregnancy. Obviously it's too late for you, but mentioning it just in case others reading this may find it helpful. A coil/IUD can be used as emergency contraception up to 5 days after unprotected sex.
If your GF doesn't get her period on time, then at that point she could do an early pregnancy test. Plan B can make a woman's next period late, so if she doesn't get it on time, it could be due to either reason.
You may be lucky, & she may have already ovulated before you had intercourse. Just have to wait & see, unfortunately. No way of knowing any sooner.
