"Almost as soon as those two pink lines pop up on a pregnancy test, your hormones get the message that something's different at mission control. Progesterone and human chorionic gonadotropin (hCG) begin pumping to signal your body to halt production on your next menstrual period, and begin forming that cluster of cells into a mini-you instead. As you probably already know, as these hormones get to work, you'll experience an onslaught of early pregnancy symptoms like nausea, fatigue, and breast tenderness.
As pregnancy progresses, our bodies produce extraordinary amounts of estrogen and progesterone, says Aumatma Shah, fertility specialist and naturopathic doctor at the Bay Area's Holistic Fertility Center. "These two steroidal hormones are key to creating dopamine and serotonin, two neurotransmitters in the brain that are important in feeling calm and happy. This is why a lot of women feel amazing when pregnant: Pregnancy offers a surge of hormones and neurotransmitters that help us feel great."
But what happens to those feel-good pregnancy hormones once your baby is born? "Unfortunately, immediately postpartum and the week following delivery, estrogen and progesterone will both plummet. Simultaneously, there will be a surge in prolactin and oxytocin," says Shah.
These wildly swinging hormones are to blame for those crazy emotions you'll experience after giving birth. Here's a closer look at what happens to your hormones postpartum and when so you know what to expect—and so you know the loony emotions you're feeling are all completely normal.
What Happens to Hormones Immediately After Giving Birth?
The birth of your sweet bundle of joy is undoubtedly one of the most exciting moments of your life. No matter how long you labor or what time you give birth—yes, even if it's at 3 a.m.—you'll likely feel an amazing, indescribable high when you meet your baby for the first time, or shortly thereafter. But those surging hormones will plummet over the next few days. Here's what's going on:
Postpartum Hormones at 3 to 6 Weeks
After those first few weeks pass, you may start to feel those rollercoaster-like emotions start to regulate a bit as you begin to get into the groove of caring for baby and get used to the lack of sleep. Ashley Margeson, a naturopathic doctor says, "the first three months are a bit of a whirlwind of sleep loss and emotions as your system runs mostly on adrenaline to move you through the day."
Around the six-week mark, she says, symptoms of postpartum depression may begin to show as those positive post-birth hormones continue to fade. "The changes you should look for closely are not wanting to shower or focus on hygiene, being afraid of leaving your baby with someone else, not being able to sleep fully due to continually checking on baby, and lack of desire for common tasks like eating, drinking, being around people, and leaving the house."
