It is possible to have an IUD even if you have never had a child, and women rely on medical devices to place an IUD as a universal choice for contraception and sterilization. In order to avoid early conception, early contraception is vital for women, both physically and mentally.

An IUD is an intrauterine device (IUD) that is inserted into the uterine cavity, thus providing contraception. The IUD acts as a foreign body, causing a mild, chronic, non-bacterial inflammatory reaction in the uterine lining, thus altering the intrauterine environment and preventing the pregnant egg from colonizing the uterus. Moreover, the IUD can stimulate the endometrium to produce prostaglandins, which cause the uterus and fallopian tubes to contract and peristalsis abnormally, and at the same time enhance the effect of estrogen, making the intrauterine environment unfavorable for implantation. The IUD can be made of metallic copper, which can achieve contraception through localized changes in the intrauterine environment such as the intrauterine lining, intrauterine fluid, and toxic effects on sperm.

Nowadays, there are various choices of IUDs in terms of material, shape and price. IUDs do not last a lifetime, and different materials have different replacement schedules.

The more common side effects after IUD are, lower abdominal pain, lumbago, and increased bleeding. Once the side effects occur, there is no need to be anxious, as long as you find out the cause and prescribe the right medication, you will usually get better. If it does not get better, it means that you are not suitable for wearing a contraceptive ring, you can choose other contraceptive methods, which can also achieve the desired contraceptive effect.

It is also possible to have an IUD if you have never had a child, but it is generally not recommended to have an IUD before having a child because it needs to be taken out six months in advance if you are ready to prepare for pregnancy next time.

I hope the above answer can help you.

It can be. Nothing major, just occasional reports of feeling sick.

There was a report of a girl who got married and just couldn't conceive, and then went to the hospital for a checkup and found out that she had an IUD (her ex-boyfriend asked the doctor to put a ring in her when she had an abortion, and she herself was never clear about it).
