Are you fertile 3 days after your period?

How old are you? You only become fertile after sex, and even then it needs to be unprotected sex. Generally for a few days after a period is the LEAST fertile time. This is the time Catholic folks schedule intercourse for practicing birth control without chemicals or pills. However, having said that, it is possible for a pregnancy to still occur but the percentage is low.


While on depo what time is the best time to try to get pregnant?

You almost cannot get pregnant during your period. The human menstrual cycle is nominally four weeks. Starting with the first day of your period, normally you will become fertile on about day 14. Your fertile period thus is at exactly the opposite end of your cycle from when you are menstruating. This does not mean that you cannot get pregnant from having sexual intercourse during your period. Normally, menstruation is 14 days after the start of your fertile period. If you have a short cycle, say 22 days, and your period is the first four days of that, and you have sex on day 4 of your period, when your fertile time starts on day 8 it will be only four days since you had sex. Sperm can live up to 6 days, and so it is possible that you will become pregnant.


Is it likely to get pregnant 5 days after your period stops if there was no protection?

Yes, pregnancy is always a possibility if you have sex without birth control. During the average 28 day cycle a woman will ovulate on day 14 (there may be a viable egg for up to 48 hours), about a week prior to ovulation a woman will produce fertile quality cervical mucus which can keep sperm alive within the vagina for up to 7 days - thus a woman may be fertile from days 7-16. Thus 5 days after menstruation a woman may be at her most fertile. Every woman's menstrual cycle is different, unless she uses fertility awareness methods she cannot kow for certain when she is fertile or not - thus birth control should always be used, if a couple doesn't use birth control in the heat of the moment than Plan B can be used up to 3 days after sex or an IUD can be used up to 5 days after sex to prevent unwanted pregnancy.


Will birth control pills change the amount of days you have your period?

How many days a girl firtile after got menstruation?

During an average 28 day cycle a woman is likely to be fertile between days 7-16 - ovulation typically occurs two weeks before menstruation (there may be a live egg present for up to 48 hours), and she is fertile up to a week before ovulation when there is fertile quality cervical mucus present. Unless a woman uses a birth control/conception method such as Fertility Awareness Method or Natural Family Planning there is no way for her to accurately determine when she is fertile, thus another birth control method should always be used in order to avoid unintended pregnancy.


Are you able to get pregnant if your period last for 3 or 4 days?

Yes, you're able to get pregnant if your period lasts for 3-4 days. How long menstruation lasts doesn't impact whether or not you can get pregnant, what matters if ovulation and the fertile phase. If you want to avoid pregnancy then always assume you could be fertile and use birth control.
