The menstrual cycle is defined by the regular, repetitive monthly occurrence of ovulation throughout a female’s reproductive life, which results from a complex feedback system involving the hypothalamus, pituitary, ovary, and uterus. The cycle has two components: the ovarian cycle, which consists of the follicular phase, ovulation, and the luteal phase; and the uterine cycle, which consists of menstruation, proliferative phase, and secretory phase. Both of these components are coordinated by hormones: follicle stimulating hormone (FSH), estrogen, luteinizing hormone (LH), and progesterone. Several different types of birth control are available to women looking to prevent pregnancy or to regulate their menstrual cycle. One of the most the most widely used type is the oral tablet also known as the birth control pill. Hormonal birth control pills contain synthetic forms of estrogen and progesterone which regulate ovulation, thicken cervical mucus, or prevent implantation of the fertilized egg. Eexamples of agents used in birth control products are synthetic derivatives of estrogen: Ethinyl Estradiol and Mestranol; and synthetic derivatives of progesterone: Desogestrel, Drospirenone, Levonorgestrel, Medroxyprogesterone, Norgestrel, Norgestimate, and Norethindrone.

Emergency contraceptive pills is called as LNG or the levonorgestrel which is taken within 3 days or 72 hours of unprotected sexual activity, Basically your expect a period after emergency contraceptive pills, maximum is say 2 weeks or 15 days. But there are times when you do not get a period after that, so such a case with negative urine pregnancy test, it doesn’t mean that it is a side effects of a pill. It just means that the emergency contraceptive pills, would have been taken very early that is early in the cycle and she would have taken. So there is nothing much to bleed. She would have spotted which she wouldn’t have realized, so there is nothing much to bleed. Second is complication of the pills, that is absent bled, so wait for couple of weeks, it will come, wait for few weeks If it doesn’t come then give a small hormonal pill and get a withdrawal bleed. so if the pregnancy test is negative, both the urine and the blood tests, then there is no periods after the emergency contraceptive pills, there is nothing to worry, just get it normally with a delayed period, withdraw it with a hormone and get it.
