  • How many weeks of pregnancy are left? 38 weeks
  • 2 weeks pregnant is how many months? You’re considered to be in the first month

With week 1 of your pregnancy complete, you’re on week 2. Enjoy it, as week 3 is on the horizon! 

One of the most exciting things about pregnancy is how many changes you’ll experience with your little one over the span of just 7 days! Here’s some tips and tricks to keep on top of all that’s happening.

Your baby at 2 weeks pregnant

What's happening in there

  • Your baby is a little too small to compare to anything just yet.
  • You’re officially at the beginning of the journey.
  • The countdown continues: you’ve got 38 weeks to go!

What happens during the 2nd week of pregnancy?

  • You've reached the end of your menstrual cycle: The gestational-week counting starts the first day of a woman’s last menstrual period (LMP), but no baby is conceived in the first two weeks. Because it’s difficult to pinpoint the exact date of conception, most doctors count back to the known LMP date (before conception) to determine the beginning of the 40-week pregnancy journey.
  • Your egg is released: During week two, your egg travels down the fallopian tubes in hopes of being fertilized by the sperm.
  • The lining of your uterus is thickening: This readies it to receive the fertilized egg.
  • You may conceive this week: It’s during week two or three that egg and sperm are most likely to unite.

Can you find out you're pregnant at 2 weeks?

  • It may be too soon to detect pregnancy at two weeks since you haven’t missed a period yet, but you can watch for signs and symptoms that may hint at pregnancy.
  • If you're considering taking an at-home pregnancy test, keep in mind that those tests work by detecting the hormone human chorionic gonadotropin (hCG) in urine. Even if you’re expecting, your body’s hCG levels may not be high enough during the first two weeks of pregnancy to produce an accurate test result.
  • While you may not be pregnant, week two is when you may be ovulating. That means you’re at your most fertile, and it can be the optimal time to try to conceive.

What should I be feeling at 2 weeks pregnant?

  • It’s early days, and you may not even be pregnant. If you are, there are going to be subtle signs that will become obvious in the next few weeks.
  • Week two pregnancy symptoms can start with a more acute sense of smell, aching or tender breasts, light spotting, and cervical mucus.

Week 2 pregnancy symptoms

During week 2 of pregnancy, your body is changing quickly. As your baby grows, you will too, and there are certain pregnancy symptoms you may experience at this time.

7 common week 2 pregnancy symptoms

  • You may notice a few subtle hormonal changes, like having a better sense of smell.
  • There may be light red or brown spotting on your underwear.
  • You may need to urinate more.
  • You could start to feel fatigued as your body starts changing.
  • As ovulation approaches—your peak fertility days—you may experience a boost in your sex drive.
  • You may feel brief lower abdomen pain. This is known as Mittelschmerz, a slight, one-sided ache or twinge in the pelvis caused by the release of the egg during ovulation.
  • At two weeks pregnant, your belly won’t show any signs of a bump yet, although you may feel a little more gassy or bloated than usual.

4 expert tips for a healthy and safe pregnancy

Being 2 weeks pregnant is an important time for you and your baby. Here’s some more expert-recommended advice on how to adjust to this new stage and keep you and your baby safe.

  1. What to look for in prenatal supplements: You should start taking prenatal supplements that contain DHA (docosahexaenoic acid) through the next nine months. The recommended amount is typically 200 mg of DHA while pregnant or breastfeeding..
  2. Take prenatal supplements early: If you’re planning to have a baby, begin taking supplements well ahead of time to help baby’s growth and development. The baby's neural tube—which later becomes the baby's brain and spinal cord—starts developing in the first month of pregnancy.
  3. Managing side effects: Prenatal supplements can come with a surprising side effect—constipation. To ease that discomfort and to promote pregnancy health, try a few simple tips to aid digestion.
  4. Give up bad habits and make changes early on: This is the time to eliminate bad habits like drinking and smoking. Studies have found a link between prenatal smoking and smaller brains in babies, so remember that every choice matters, no matter how early you are into your pregnancy journey.
