Pre-primary women:

Pre-primary refers to the period before the first childbirth, including adolescent girls. Before giving birth, it is advisable to choose a contraceptive method that will have little impact on future reproductive functions and is less susceptible to infection. The period before first childbearing can usually be divided into two periods: the period of first sexual intercourse (generally referred to as the newlywed period) and the period after sexual intercourse (2-3 months after engagement).

When having sex for the first time, because the female’s reproductive tract is relatively tight and both parties lack sexual experience, it is advisable to use short-acting oral contraceptives, male condoms, etc. If you have unprepared sexual intercourse, you can take emergency contraceptive pills first, followed by short-acting oral contraceptive pills or male condoms. If the female reproductive tract expands after a period of sexual intercourse, you can also choose female condoms, external spermicides, vaginal contraceptive rings, etc.; or use a combination of safe period and barrier contraception, such as in "Dangerous Use condoms during the "safe period" and use topical spermicides during the "safe period".

It is generally not advisable to choose an intrauterine device before the first childbirth. In special circumstances, it should be selected under the guidance of a physician. It is generally not advisable to use long-acting oral contraceptives or long-acting contraceptive injections before the first child is born, because it takes longer to resume childbirth after discontinuation of these long-acting contraceptive preparations.

(4) Condoms, and some easily soluble external spermicides, such as jelly, gel, etc. It is not advisable to use combined oral contraceptive preparations during postpartum lactation because estrogen may affect milk secretion. It is also not advisable to use difficult-to-dissolve external spermicides during breastfeeding, such as external contraceptive tablets and pills, because lactating mothers have less vaginal secretions and are not easy to dissolve.
