  • Week 2 – Ovulation occurs, which is the best chance of getting pregnant.


  • Week 3 – You can be pregnant but will not experience any symptoms.


  • Week 4 – The pregnancy test will come out positive if you are indeed pregnant. Hormones slowly increase, including hCG.
  • Week 5 – The embryo is only about the size of a grain of sand, and some organs start to develop. The embryo is the unborn child inside your womb.
  • Week 6 –The realization of being pregnant finally kicks in, and worries about miscarriage come in. This is also when anxiety and depression may inflict you because of your negative thoughts.

  • Week 11 –Weird cravings begin, and you’ll be gaining some weight.
  • Week 12 – Your uterus begins to expand in the outside of the protective pelvic bones and is continually growing. You’ll also notice skin changes, such as the darkening of your areolas and the appearance of the ‘mask of pregnancy’ or chloasma.

  • Week 27 – You’ll probably be gaining about 1 pound a week.
  • Week 28 – Welcome to the third trimester!
  • Week 29 – The lump in your belly may stop you from certain activities. You’ll need to get more rest and more nutrients for you and your baby.
  • Week 30 – You will be out of breath most of the time since the growing uterus will crowd over your diaphragm.

  • Week 32 – Pregnancy may be starting to lose some of its glow.


Important Things To Remember On Your 32nd Week

This stage will be tiring, but just keep it in your head that you’re a few months closer to meeting your newborn. Your shortness of breath becomes more frequent, and your blood volume increases to about 50%. You must see your doctor every two weeks.

  • Week 33 – Don’t get too married to your dream delivery. Sometimes your amniotic fluid leaks, but don’t worry because this is not uncommon during week 33.
  • Week 34 – You may be driving yourself crazy about the baby’s necessities. Keep it in perspective.
  • Week 35 – There’s a chance the body has this Group B streptococcus bacteria. Be extra cautious. Also, you may want to start counting your baby’s kicks.
