Start a pregnancy on the pill is possible, although this is extremely rare. Back on this paradox.
How does a pill?
A pill "classic" combines two hormones, a progestin and an estrogen, which alter hormone levels in women. In this way the pituitary gland (a small gland in the brain) "believes" that the woman is already pregnant and therefore does not stimulate the ovaries to produce an egg.
The pill usually comes in the form of platelets of 21 tablets that are taken daily, spacing two plates by seven days off. "Rules" of frustration pill arrive at the break.
When we start a wafer after seven days of uninterrupted pill (seven pills in a row), the pituitary gland is fooled. This is why a forgotten pill over 12 hours (or more than three hours for micro-progestin) during this first week is more risky than forgetfulness during the second or third week of the wafer. On or risk of pregnancy as you're taking the pill!
What risks of getting pregnant on the pill?
Women taking the pill have very little chance of getting pregnant, unless:
They have forgotten the pill within a certain period from the date of the report,
They took a break of more than seven days or took less than 21 tablets,
They have had vomiting or severe diarrhea within four hours after taking the pill,
They have taken medication that may affect the effectiveness of the pill (TB, barbiturates, anti-asthma). Before treatment, tell your doctor so the type of hormonal contraception that you follow.
A forgotten pill (even one) always leads to a risk of pregnancy if there was unprotected sex (or the condom broke down) within 5 days before forgetting or within 7 days (depending on type pill, the risk can take the time to a plate).
Sometimes, very rarely does one get pregnant even if we never forgot to take her pill. Remember that it is effective "only" 99% ... Sylvie says: "I got pregnant on the pill three times, each time with a different pill and without forgetting! Subsequently, my doctor told me that my liver could not handle the pill and suddenly he evacuated, hence its inefficiency ... I had to change means of contraception. "
Pregnant on the pill, what are the signs?
You can not rely on the absence of rules as pregnant women on the pill often continue to menstruate the first three months of pregnancy! They may even have rules "anniversary" every month until birth. By cons, if they are attentive, they will notice that these rules are less abundant and mostly darker than usual.
Other common signs of pregnancy (tension in the breasts, nausea ...) are not mandatory ... or may be due to the pill itself! So if there was a relative risk, the best way to be sure is to test before starting a new pack. And for those who would not be so unhappy that an "accident", know that even pregnant on the pill can carry the pregnancy to term without risk to the baby.
