I don't think it's impossible.
For one thing, sperm can remain viable in the fallopian tubes for up to 7 days after intercourse. So the real question might be can a woman get pregnant ten days after her period has finished. Of course, the answer to that is yes.
Absolutely! If you ovulate soon after your period. A man's sperm can live for up to three-five days in a woman's body, a woman can get pregnant anytime of the month even while on her period.
Normally a woman is most fertile (ovulation) 3-5 days before her period and 3 days after her period.
Actually, most women on a normal 28 day cycle with their periods will ovulate approximately 14 days into her cycle. For example the first day you start your period is cycle day 1. So you would count from the first day you started your period to 14 days and that is when it is possible to get pregnant. From cycle day 13-17 I would be very careful if you were trying to avoid pregnancy.
In the 2005 NIH study, Wilcox and his colleagues studied the menstruation cycles of 213 women, most between the ages of 25 and 35, when a woman's cycles are most likely to be regular. They found that a woman's fertile period can extend to the day when menstruation is predicted to begin. In addition, they found that a woman can become fertile as early as day 4 of her cycle, and that 17% are fertile by day. Therefore, menstruation is no guarantee that a woman will not become pregnant when engaging in sexual intercourse.
Here is a really good forum on BIRTH CONTROL MYTHS
There are birth control methods that are medically proven to be effective in preventing an unwanted pregnancy. There are also many other methods that some people think will work to avoid pregnancy, which don't work. We're glad you're reading about birth control methods. We think it's just as important for you to know what doesn't work as what does. If you don't want to get pregnant, don't believe or practice any of the following so-called birth control methods.
Several myths, or stories, about birth control deal with what is supposed to be the "safe" time of the month for a woman. Maybe you've heard that a woman can have intercourse without worrying about pregnancy three days before and three days after her period. Or that she can't get pregnant during her period.
NONE OF THIS IS TRUE. Unless you are using a medically proven effective method of birth control, she could get pregnant any time of the month that she has sexual intercourse. There are several reasons for this. Even if a woman's periods are pretty regular, she can never be sure when her ovaries are releasing an egg. Ovulation, the release of the egg from the ovaries, has nothing to do with when you had your last period. It depends on when you will have your next period, which is something you can never be sure of. Especially for younger women, this is a very risky approach to birth control, because for the first few years in the woman's periods will probably be very irregular.

As we all know, pregnancy results from when a sperm joins with an ovum and successfully plants itself in the uterous. A woman can ovulate, even during her period, and, especially if her period is on the long side, she may very well ovulate before all of the blood has stopped trickling out.
Pregnancy will occur if the uterous has finished it's expelling of menses and the embryo is able to plant itself. If it is at the beginning of the period, then the fertilized egg will most likely get pushed out with the rest of the fluids before it is able to implant. Hence the myth that you can't get pregnant during your period---you can concieve, but whether or not the egg can stay attached and develop into a fetus is the question.
I think people can ovulate close in time.. especially if I changed my thyroid dose ior other hormone things being off.
I think it could be possible.
