These synthetic hormones enter the brain and shut down the hormones such as gonadotropins which are responsible for the proper functioning of the menstrual cycle. Due to this ovulation is prevented and it causes menstrual irregularities. Synthetic hormones do not limit binding with just the progesterone receptor, but many other receptors as well. When these synthetic progestins binds to the wrong receptor, that receptor may convey inaccurate signals, which throws the body out of balance, causing irregularities.

Disrupted ovulation

Post-pill Amenorrhea is a common problem for many women taking birth control pills or birth control shots.

Birth control shots like  Depo-Provera are taken by many people as a birth control method every 90 days. Even if you stop Birth control shots, even then it may hinder fertility for about 22 months or more.

Changes the uterine lining

Birth control methods change the uterine lining and this makes the uterine lining unreceptive to implantation that happens after the egg is fertilised by the sperm. Synthetic hormones control the body’s estrogen progesterone which makes it difficult for a proper uterine lining to be formed. These deplete the glycogen into sugar and makes the endometrium lining thin. Many women start using birth control methods at a very young age and this goes on for a longer time. They are unaware of the probable  side effects of the birth control method that may become serious after continuing it for a longer period of time. So, you must know about the probable consequences you may have to face after taking birth control methods so that you don’t have to suffer.

Cervical mucus changes

The Pill taken for birth control are shown to thicken cervical mucus so that sperm cannot reach the egg. Healthy cervical mucus is quite necessary for conception because it helps sperm to travel through the vagina and the cervix to meet and fertilize an egg, thus causing fertilization.  But cervical mucus changes may persist for a longer time even after you stop using the birth control method. This may hinder your fertility as the cervical mucus may remain thick and the sperm may not reach the ova. This may make it seem that you have lost your fertility, but it is not so. It’s just a thickening of cervical mucus which can always be treated by the help of proper medication.

So, these are the probable issues you may have to face if you are using a birth control method, specially contraceptive pills. Generally a woman regains her fertility within a month or three months but it may end up for a longer period of time due to the above mentioned problems. This this may hamper your family planning. Many people think that this is permanent and feel dejected but you can always regain your fertility after taking help from your doctor. So,  if you have decided to stop birth control and be fertile again, it may take some time for you to be  back to normal. So, don’t panic, consult your Doctor instead.
