The first period after a miscarriage is actually usually late. Some interpret this lateness as a sign of pregnancy, but it is simply a woman’s body recovering from the trauma.

Six month old babies are very in tune with the emotions of people around them, such as their parents or siblings. When someone is happy or sad, the baby may reflect that emotion through their facial expressions or noises (cooing, laughing, versus crying).

Folic acid helps prevent neural tube defects (NTDs)—serious birth defects of the spinal cord (such as spina bifida) and the brain (such as anencephaly).

Other causes of infertility include poor sperm quality, sperm not moving well (poor motility), or not having enough (or any) sperm to begin with.

Chronic infections in the cervix can also reduce the amount or quality of cervical mucus, the sticky or slippery substance that collects on the cervix and in the vagina. Reduced amount or quality of cervical mucus can make it difficult for women to get pregnant.

Hypothalamic amenorrhea occurs when the hypothalamus, a gland in the brain that regulates body processes, slows or stops releasing gonadotropin-releasing hormone (GnRH), the hormone that starts the menstrual cycle.
