Understand your concerns. Yes dear It will be harmful in the future. It is not like that, you will be infertile 100%,but it is increasing chance of ABORTION, hormonal imbalance and infertility. Do not use emergency contraception as a regular contraception. So I advised you to use some other contraceptives method or avoid unprotected sex. Use condom, diaphragm, injections, patches...which will not affect your reproductive system. I hope this will help you. Thanks Chat Doctor. </s>
