Probability of conception after childbirth is a vital question for those, who do not hurry to conceive a new baby right after birth of the first one


Probability of conception after childbirth is a vital question for
those, who do not hurry to conceive a new baby right after birth of the first
one. However, there`re also other cases (although not so frequent): parents want
age difference between children to be as much smaller; unfortunately, tragic
circumstances also happen (for example, induced abortion connected with
serious fetal deformity or high risk for a mother`s life). Regardless of
reasons that cause your interest towards probability of conception after
delivery
, first of all, it`s useful to understand what happens with
ovarian-menstrual female cycle during post-natal period.

 

 
During pregnancy a woman`s pituitary starts producing mammotropic hormone,
preparing breasts for lactation, stimulating lactation and at the same time
suppressing ovulation. When a baby is nursing, secretion of mammotropic hormone
intensifies, and as interval between feedings increases - it falls. As a rule,
while a woman is breastfeeding a baby, mammotropic hormone suppresses
ovulation completely - and then lactation amenorrhea appears (absence
of menstruation during breastfeeding period). However, there are also cases,
when menstrual cycle is restored quite quickly while sufficient lactation. We
can state the following concerning probability of conception.

 

 
Firstly, it`s almost impossible to determine any rules as for terms of
conception ability recovery. I.e., of course, it is known that breastfeeding
causes delay of ovulation, however, you cannot foretell term of the
first post-natal ovulation exactly. Terms of ovulation recommencement after
delivery are very individual. Moreover, they can be different for same women
after different deliveries, so you should not rely on your previous experience
in this question. The main index of ovulation recommencement - is the first
post-natal menstruation. Menstruation starts earlier in women, who do not
breastfeed their babies and it starts on the 7th week in breastfeeding
women.
 
Not to miss the first post-natal ovulation, it is recommended to use
temperature test. Breastfeeding women should start measuring basal body temperature
since 6th week after delivery, and those who don`t breastfeed -
since 4th: not to miss the moment of its increase, as it is a sign
of ovulation.

 

Secondly, after menstruations are restored, anovulatory cycles can
take place (i.e. menstruation without ovulation).

 

Thirdly, absence of menstruation does not mean a woman cannot conceive.
The matter is that moment of conception can fall right on the middle of just
restored cycle.

 
It is noted that while appearance of following pregnancy, a baby often
refuses from maternal milk. They suppose that the following mechanism of a
baby`s refusal from breast works here.
 
When a baby starts nursing, hormone ocytocin
is produced in mother, and it stimulates contraction of unstriped muscles.
This leads to contraction of end canals of lacteal glands (milk is like
“injected” in as baby`s mouth). Uterine muscles are also contracted at the same
time.

 
This is very useful after delivery, but in case of a new pregnancy
uterine hypersthenia can lead to miscarriage. So,
probably, with coming of following pregnancy secretion of oxytocin is
lowered, that a baby feels difficulties while nursing. Besides, under the
influence of hormonal changes in organism, accompanying coming of pregnancy,
milk taste can change also.
 
However, there`s no regular connection between a
baby`s refusal from breast and repeated pregnancy.

 

Modern medicine states that for complete recovery of female organism
after delivery interval between childbirth and following pregnancy should be at
least 2 years, although, of course, this is rather a recommendation, not an inviolable
rule.
