o, you think you might be pregnant? Whether this is a surprise or a monumental achievement after months and months of tireless efforts, this list can help you determine if there really is a bun in the oven.
We’ve broken down the list into the following categories:
DUH.
If you are still not convinced that you are pregnant after reading this section… then "pregnancy brain" has hit you a bit early.
REALLY? THAT’S FASCINATING!
Metallic Taste
If you suddenly feel like you’ve just chewed some aluminum foil, you’re not alone. While some might dismiss this symptom as a side effect of your prenatal vitamins, others credit this metallic taste to your body’s release of toxins. Another explanation? The increase of hormones during pregnancy affecting your sense of taste.
Montgomery’s Tubercles
This is the fancy name for the small bumps that are around the perimeter of your areola. They start to become visible — or raised — as your body's way of (already!) getting ready for breastfeeding.
Constipation
The fun begins early on! That wacky progesterone is at it again — putting your intestines "to sleep" to decrease motility.
Raised Basal Body Temperature
If you weren’t "charting" during your effort to conceive, you might be surprised to learn that your temperature rises right after ovulation and stays at that level through the luteal phase of your cycle (the two weeks after ovulation) until your next period. When you’re pregnant, your temperature stays elevated.
Spotting or Cramping
You might be discouraged to see some spotting or experience some cramping, but it doesn’t always mean that your period has arrived. In fact, when your fertilized egg nestles itself into your uterine wall about 6-12 days after conception (known as "implantation"), this could result in minor spotting that is lighter in color than you would expect with your period.
Vaginal Discharge
Early in pregnancy, you’ll probably experience a thin, milky white discharge. Called “leucorrhoea,” this substance will increase during pregnancy and is completely normal.
Skin Changes
Melasma or chloasma – sometimes referred to as the “mask of pregnancy” – can develop during the first trimester. This “mask” describes a discoloration of the skin, usually on the forehead, cheeks, and/or nose. (Women with darker complexions experience this more often than fair-skinned women.)
Lightheadedness/Headaches/Dizziness Oh, those hormones! Now they’re increasing your blood circulation and dilating your blood vessels, causing possible lightheadedness, headaches, and/or dizziness.
I WAS WONDERING ABOUT THAT…
Fatigue
Most likely related to the hormone progesterone, you might feel knocked out as early as a week after conception.
Change in Sense of Smell
You might suddenly notice aromas you hadn’t before, or your favorite smells could start making you feel ill. Don’t be alarmed; this is a common symptom of pregnancy.
Breast Tenderness
If you normally welcome the arrival of your period with the arrival of slightly swollen or tender breasts, this symptom of pregnancy might surprise you, especially since it could begin at about the same time you would be expecting your period to arrive.
Darkened Areolas
Right around the time that your breasts might start to feel tender, you might also notice that your areolas (the darker area around the nipple) are already beginning to darken, and possibly even widen in diameter. It is said that these changes help the newborn find his “target” for breastfeeding.
Frequent Urination
While this symptom usually kicks in full force during the third trimester (when your growing uterus is pressing on your bladder), you can start feeling the need to visit the loo more often as early as 6-8 weeks after conception.
Nausea and Vomiting
These symptoms – the ones most commonly associated with pregnancy – can begin as early as two to eight weeks after conception. This time, the hormone to blame is estrogen… along with that wonderful sensitivity to odors, which can trigger a bout of nausea.
Mood Swings
It’s either funny or ironic that mood swings could be either a sign of pregnancy – or PMS! Time to blame those hormones again.
DUH.
Positive Over-the-Counter Pregnancy Test(s)
If you can’t wait until you’ve missed your period, you can test with an at-home urine pregnancy test as early as 10–14 days after conception. (We added the plural above since we are quite familiar with talking multiple tests when you really want that confirmation!)
Positive Blood Test for Pregnancy
If you’re one of those women who can “sense” that you're pregnant, you can confirm this suspicion with a blood test as early as 8-10 days after conception.
Ultrasound Confirmation
This would be a pretty strong indication of whether or not you can start day-dreaming about decorating the nursery.
Missed Period with Any Combination of the Above
Of course, there are many reasons why you could miss your period, but if you’ve missed your period and have a positive pregnancy test or ultrasound confirmation, it might be time to break out the sparkling cider. Congratulations!
