How to prevent pregnancy without condoms?

For many young couples of the new generation, most of them hope to have fun for two years without any burden after marriage before having their own baby. However, they do not want to be restrained by condoms during sex, and contraceptives are harmful to health. Only by choosing a suitable contraceptive method can they ensure their health. Therefore, how to prevent pregnancy without condoms is a problem. So how can we prevent pregnancy without wearing a condom?

Electric contraceptive: American medical scientists have ingeniously developed a tiny electric contraceptive device that is inserted into the uterus. When sperm passes through, the low electric field it releases kills the sperm.

Olfactory contraceptive method: an aerosol olfactory contraceptive, which is fragrant and sweet. While lovers are admiring the "flowers" and smelling the "fragrance", their sperm and eggs have died.

Bra contraception: A flashing contraceptive bra with a microelectronic system that can predict ovulation in advance based on changes in body temperature to achieve the purpose of contraception.

Necklace contraception: The woman's body temperature is transmitted to the micro sensor in the necklace to test the contraception during the safe menstrual period. If it is safe, the green light will turn on, otherwise the red light will turn on.

Contraceptive watch: An electronic contraceptive watch produced in Switzerland, which can display the menstrual cycle, ovulation period, contraceptive safety period and pregnancy risk period when worn.

Subcutaneous contraception: One or several capsules containing contraceptive drugs are buried under the skin of the forearm, releasing a certain amount of hormones every day, which directly act on the ovaries and pituitary gland to achieve contraception.

When is ovulation and how to determine it?

1. Calculate by yourself

1. Ovulation period. It refers to the period when a woman may ovulate, that is, counting back 14 days from the first day of her menstruation, the 4 days before and 5 days after the 14th day, a total of nine days, is the ovulation period, also known as the dangerous period.

Calculation of your ovulation period:

For example, if your period comes today (the 27th) this month, and your period was on November 30th last month, your menstrual cycle is 27 days, so the first day of your next period should be January 24th, 2008. Subtract 14 days from January 24, and January 10 is the ovulation day. The ovulation day and the 5 days before and 4 days after it, that is, January 5-14, is the ovulation period.

2. Safe period. There is basically no ovulation in the seven days before and eight days after menstruation, so the "15 days in total" is the safe period.

The possibility of getting pregnant during the safe period is very small, only about 1-5% (that is, the probability of not getting pregnant is 95%-99%), and the accidental pregnancy rate of most contraceptives is 10% (that is, the probability of not getting pregnant is 90%).

From the above, we can see that how can we prevent pregnancy without wearing a condom? The most common method of contraception without condoms is taking birth control pills and doing it during the safe period. But these are not absolutely safe practices, and some of them may be harmful to your health. Therefore, you should make choices based on your own situation and not harm your body and make yourself regret it.
