Can breastfeeding interfere with your pregnancy if you do get pregnant? It is generally considered safe to continue to breastfeed once you become pregnant. However, some women may experience cramping due to the release of small amounts of oxytocin (the same hormone that causes contractions) during breastfeeding.
If a woman conceives again within the first year after giving birth, the signs of pregnancy while breastfeeding may go unnoticed. Breastfeeding mothers often experience a number of changes in their body, leading to discomfort and sensitivity, and also will not have a regular menstrual cycle.
Many mothers wonder whether breastfeeding will affect the reliability of pregnancy tests. It does not — pregnancy tests measure the amount of the hormone hCG (human chorionic gonadotropin) in blood or urine, and hCG levels are not affected by breastfeeding.
Postpartum hormones 6 months after delivery
However, this change depends on your baby's nursing patterns and if you've begun to wean. That's because this hormone stays high while breastfeeding, but it comes down as you introduce your baby to solids and start weaning.
Yes, it's possible to get pregnant any time from about three weeks after giving birth. This is true even if you're breastfeeding and haven't had a period yet. Many women are less fertile while they're breastfeeding, especially in the early weeks and months.
Chance of pregnancy is practically zero during the first three months, less than 2% between 3 and 6 months, and about 6% after 6 months (assuming mom's menstrual periods have not yet returned). The average time for the return of menstrual periods is 14.6 months.
There's no need to wean your baby: You can breastfeed and prepare for your next pregnancy at the same time. Many breastfeeding mothers find that once they go back to work or the coveted full-night's sleep becomes a reality, ovulation starts up and they begin to menstruate again.
Previous twinning studies
Steinman found that women who become pregnant while breastfeeding are nine times more likely to conceive twins than women who are not breastfeeding at the time of conception.
This is why fraternal twins run in families. However, only women ovulate. So, the mother's genes control this and the fathers don't. This is why having a background of twins in the family matters only if it is on the mother's side.
Factors that increase the chance of twins include: consuming high amounts of dairy foods, being over the age of 30, and conceiving while breastfeeding. Many fertility drugs including Clomid, Gonal-F, and Follistim also increase the odds of a twin pregnancy.
Serum β-hCG level was significantly higher in breastfeeding group compared to the nonpregnant control (P < 0.05), but lower than that of the pregnant control (P < 0.05).
If you practice ecological breastfeeding: Chance of pregnancy is practically zero during the first three months, less than 2% between 3 and 6 months, and about 6% after 6 months (assuming mom's menstrual periods have not yet returned). The average time for the return of menstrual periods is 14.6 months.
Breastfeeding has a demonstrable influence in inhibiting ovulation; it is not surprising that it has an inhibiting effect on fertility. According to Perez, during the first 3 months when a woman is nursing, there is higher security provided agaist conception than most contraceptives.
You can get pregnant as little as 3 weeks after the birth of a baby, even if you're breastfeeding and your periods haven't started again. Unless you want to get pregnant again, it's important to use some kind of contraception every time you have sex after giving birth, including the first time.
Prolactin also prevents menstruation. Breast-feeding keeps these hormone levels high, so the longer you nurse, the more likely you will experience a light period, or no period at all. On the flip side, as you wean your baby off of breast milk, your periods will likely return relatively quickly.
Irregular periods are also an aftereffect of pregnancy and breastfeeding. Your period is most likely to resume if your baby no longer requires night-time feeding because they are sleeping for six or more hours. If your baby is feeding less or has started eating solid foods, your period will return soon.
Can you hold a newborn on your period? Since mom herself will be back on her period soon, there's no valid, medically-proven reason that someone's menstrual cycle would cause any harm to a newborn.
Breastfeeding only prevents pregnancy for up to 6 months.
But breastfeeding isn't a long-term natural birth control method — you can only rely on breastfeeding to prevent pregnancy for the first 6 months of your baby's life. Sometimes, you might get your period even before that.
