1. At what time can you get pregnant after your period?
Sperm can live inside a woman's uterus for up to 5 days after sex and conception can only happen if there are sperm in the uterus or fallopian tubes during ovulation.
For women with shorter cycles, there is still a chance of pregnancy if you have sex during your period. If you have sex at the end of your period and you ovulate early, there is still a chance of conception. Using birth control or other protection is always the safest way to prevent pregnancy.
2. How does ovulation and pregnancy happen?
Ovulation occurs about once a month, the egg is released and released into the fallopian tube. Then move towards the sperm waiting in the fallopian tubes and uterus. Eggs can survive for about 12-24 hours after leaving the ovary. Meanwhile, sperm can live up to 5 days from the time of sexual intercourse. Egg implantation occurs after fertilization, usually 6 to 12 days after ovulation. If you're tracking ovulation and waiting 36 to 48 hours after you ovulate, the chances of conception are low. The chance of getting pregnant decreases in the month after ovulation. If there is no conception and implantation, the lining of the uterus will shed and menstruation will occur.
3. Method of calculating the date of safe sex
To predict the first day of conception (when you might get pregnant) in your current cycle:
Find the shortest cycle in your previous record. Subtract 18 from the total number of days in that cycle. Count that number from day 1 of your current cycle and mark that day with an X. (Include day 1 as you count.) Days marked with an X are days your first conception.

For example, if your shortest cycle is 26 days long, then 26 minus 18 you get 8. Then count 8 days starting from day 1 (first day of your period). If day 1 was the 4th day of the month, you would mark an X on day 11. So since day 11 is the first fertile day of this cycle, you should stop having vaginal sex on this day or start using another method of birth control.
To predict the last date of conception in your current cycle:
Find the longest cycle in your record. Subtract the total number of days from that period by 11. Count that number from day 1 (first day of your period) of your current cycle and mark that day with an X. (Include day 1 as you count. ) The date marked X is the date of last conception. For example, if your longest cycle is 30 days, subtract 30 from 11 and you get 19. Then count 19 days starting from day 1. If day 1 is the 4th of the month, you'll mark an X with an X. on day 22. So since day 22 is the last fertile day of this cycle, you can start having unprotected sex the next day.
4. Sex on safe days, can you get pregnant?
Safe days for women can only predict days that are most likely to be safe and unsafe days, but cannot tell you for sure exactly when you will conceive. So if your cycles are not always of the same length and you can't use it at all if all your cycles are shorter than 27 days then the safest way to calculate relationship days is indeed. difficult to use. Safe sex days work best when combined with other fertility tests, like temperature and cervical mucus.
