From the 31st of last month to the 2nd of August of next month. To 16 is not a safe period

14 I just don't know if I am not in the safe period

The safe period is one week before and after menstruation.

Counting from the first day of menstruation, the 14 days backward or subtracted 14 days is the ovulation day, and the ovulation day and the first 5 days and the next 4 days together are called ovulation. Here it is.

Rationale for rhythm contraception. For example, if a woman's menstrual cycle is 28 days, and the first day of this menstrual period is on December 2, then the next menstrual period will come.

The tide is on December 30 (December 2 plus 28 days), and then subtract 14 days from December 30, so December 16 is the day of ovulation. Ovulation is the day of ovulation and 5 days before and 4 days after, that is, December 11-20. Except for the menstrual period and ovulation period, the rest.

The period of time is a safe period.

If the menstrual period is 28-30 days, the first day after menstruation, the 10th day, the 20th day, and the 30th day after menstruation, these 20 days are the safe period.

It is essential to know when the next menstrual period will be in order to calculate the safe period.

The safe period is generally in the first seven and eight days of a woman's menstruation, so the possibility of pregnancy cannot be ruled out, the probability of pregnancy is not easy to say, this is unknown, and you can only test it after 3-7 days after your next menstrual period.

Oh, the friend above is very detailed, let me tell you, if you are really not at ease, you can buy the pregnancy test to test it, you are sure, don't you? I bought one before and went to ** a company called: hyhhm12345 which is good I went to buy it and I am very relieved Oh hehe.

If the menstrual period is regular, more than 28 days, the first seven and the last eight, from the first day of menstruation. Generally, 0 3 days after menstruation is a safe period, and the 4 to 8 days enter the dangerous period. A short cycle (23 27) or a long period (6 7 days) with clean menstruation enters the danger period.

Coming on the 11th of last month, the 7th of this month is the 28th day of the cycle, 28 7 35 days, if the usual cycle never exceeds 35 days, the 7th is the safe period. The 7th belongs to the safe period after ovulation, "the first seven, 7 days before the next menstruation" This is a very uncertain statement, the key is to be most sure when the next menstrual period will come. Therefore, if you calculate scientifically, you will be given a range, which days may come, for example, the next time it will be 9 or 13, with the 13th as the benchmark, and the first 7 days is the safe period.

Yes. But nothing is absolutely safe. It's just that it's more secure.
