Yes, it is possible to get pregnant when you have unprotected sex during your periods but the chances are slim. The menstrual cycle of women is highly unpredictable and varies for each woman. Some women have regular menstrual cycle while others have irregular periods. Every woman understands their own body cycle and the knowledge of their menstrual cycle helps them in either conceiving or in preventing conception.
During period the body sheds the uterine lining that has been building up from the previous month in preparation of pregnancy. The small uterine contraction begins to encourage the unused endometrium and unfertilized egg to be shed from the uterus via the vagina when you don’t become pregnant and this happens in each cycle.
Some women ovulate at the very end of their menstrual cycle so if you have had intercourse and the sperm is still alive in your body it could be able to fertilize an egg.
When an egg and a sperm meet in the fallopian tube, conception happens. Typically, for a 28 day menstrual cycle an egg reaches maturity in one of the two ovaries most likely between the 12th and 16th day. An egg can outlast in a fallopian tube for about 24 hours after it is emitted by the ovary. The egg is shed along with the uterine lining during the periods if it isn’t fertile. So, you can only get pregnant during your period when the sperm are present in the fallopian tube.
When a mature egg is released from the ovary and is pushed down the fallopian tube it is ready to be fertilized. The lining of the uterus prepares for the fertilized egg by thickening. The uterine lining along with blood is shed through the vagina when no conception takes place.
Women ovulate around 12th to 16th days before the onset of their periods though the menstrual cycle is not always predictable. Women who have regular periods can also have off cycle and ovulate either earlier or later. If a woman ovulates early say on the 10th day of the cycle and you have had intercourse during your period than it is possible that you might conceive.
Short Menstrual Cycle
Many women have a short menstrual cycle, as short as 22 days. If you are one of those women who have a shorter cycle than you would ovulate just a few days after your periods. As it is known that a sperm can survive in a reproductive tract for up to three days so, there are chances of the sperm to be there till you ovulate, thus making it possible for you to get pregnant on your periods.
Long Menstrual Cycle or Irregular Bleeding
Some women have longer menstrual cycle and even have irregular bleeding in between or after the periods. If a woman has had unprotected sex while she was still on her periods there are chances of her getting pregnant. A woman is fertile even if she is spotting and she might be approaching ovulation while she is still on her periods. So a woman might get pregnant if she ovulates shortly after her period ends or even while she’s on her periods.
Ovulation bleeding is sometimes mistaken for long or abnormal periods. It is fertile cervical fluid that occurs close to ovulation. Many women experience brown or red spotting just before their ovulation time and it provides the ideal setting for a sperm to live in. So if you have had intercourse while you are having ovulation spotting there is a good chance of you getting pregnant.
Can I Ovulate during my Periods?
For women who have regular menstrual cycle it is highly unlikely for them to ovulate during their periods but for women who have irregular periods either short or long cycle can have an odd occurrence of ovulating during their periods. The chances for them to ovulate are also unlikely but as a sperm can live in the body for around 3 to 5 days, getting pregnant is possible if you have had unprotected sex during your periods.
Can I Ovulate more than once during each Cycle?
No, a woman cannot ovulate more than once during each cycle but multiple ovulations can occur when two or more eggs are released in a single cycle. These eggs are released during 24 hour period in as many as 5-10% cycles and result in fraternal twins.
Can I get Pregnant during my Period while on Birth Control?
If you are on the pill or implant you cannot get pregnant. Even if you were not on contraception it is highly unlikely that you might get pregnant during your periods. You can get pregnant only when your body is ovulating and the contraception stops your body from ovulating.
It really depends on how long or short your menstrual cycle is. If you have a 28 day cycle you will ovulate between 12th and 16th day of your cycle and if your period last for say seven days then by the time it finishes you might be just a few days away from ovulating.
If you have shorter menstrual cycle say 22 days than you might ovulate just a few days of your period. In both cases if the sperm is in the fallopian tube then there are chances of you getting pregnant just after your period.
Can I get Pregnant just before my Period?
Most women do not get pregnant if they have had unprotected sex just before their periods but not every woman has regular menstrual cycle so it is possible for a woman to get pregnant before her periods too.
So, it can be said that there is no such time during the menstrual cycle when you are not at a risk of getting pregnant. Every woman and their menstrual cycle differs so tough the chances of you getting pregnant during your period are highly unlikely but it cannot be completely ignored.
