There's no single "hardest" month, as it varies, but the third trimester (months 7-9) is often cited as the most physically uncomfortable due to the baby's size causing pressure, pain, sleep issues, and frequent urination, while the first trimester (months 1-3) is tough due to extreme nausea, fatigue, and hormonal shifts, and the second trimester (months 4-6) is usually the "easiest" "golden period" before the final discomforts set in.
Third trimester (weeks 27 to week 40): The third trimester is the most uncomfortable for most women because the fetus is heaviest. The added weight places pressure on your joints, bladder and gut. You may notice new aches and pains and struggle with heartburn, constipation or dribbling pee.
The "worst week" of pregnancy varies, but many women find the first trimester, particularly weeks 8-10, to be the most challenging due to intense morning sickness (nausea/vomiting peaking with hormone surges), extreme fatigue, and heightened emotional changes, though some experience severe symptoms like hyperemesis gravidarum (HG) requiring medical attention, while others face discomforts in later pregnancy.
Second trimester (week 13–week 28)
Most women find the second trimester of pregnancy easier than the first. But it is just as important to stay informed about your pregnancy during these months.
First Trimester (0 to 13 Weeks)
The first trimester is the most crucial to your baby's development. During this period, your baby's body structure and organ systems develop. Most miscarriages and birth defects occur during this period. Your body also undergoes major changes during the first trimester.
The "3-2-1 Rule" in pregnancy is a guideline for first-time mothers to know when to call their midwife or doctor for active labor: consistent contractions every 3 minutes, lasting 2 minutes each (or 1 minute long for some variations), for over 1 hour. It helps differentiate true labor from false labor (Braxton Hicks), signaling it's time to head to the birthing center, while subsequent pregnancies often follow the faster 5-1-1 rule.
What week do most miscarriages happen? More than 80% of miscarriages happen during the first trimester or by the end of the 14th week.
The second trimester of pregnancy is often the most enjoyable. Find out how to relieve common symptoms — and consider ways to prepare for what's ahead. The second trimester of pregnancy often brings a renewed sense of well-being. The worst of the nausea often is gone.
At 14 weeks pregnant, you've made it to the second trimester! Often called the “golden” period of pregnancy, the second trimester may bring some relief to those uncomfortable pregnancy symptoms such as morning sickness and fatigue, giving you a much-needed boost of energy at 14 weeks and onwards!
You've made it to your last trimester. The third trimester is the shortest, and includes weeks 28-40. We're sure you're feeling all kinds of emotions now that you get to meet your baby soon! During these last few months, it is time to organize everything before your baby gets here.
It's normal to feel more tired than normal while pregnant. In fact, most women find they need a great deal more sleep, and this happens the most during the first and last trimesters. The good news is some moms have a big energy boost during the second three months, when they stop feeling as sick.
There's no perfect time to share your pregnancy—do what feels right for you. Many wait until after the first trimester. Miscarriage risk drops after 13 weeks, but it's also OK to tell trusted loved ones earlier for support.
Weeks 1 & 2
One of the greatest risks to pregnancy at this stage is a blighted ovum which causes about half of the miscarriages between two and six weeks (often before the woman knows she is pregnant).
The "worst week" of pregnancy varies, but many women find the first trimester, particularly weeks 8-10, to be the most challenging due to intense morning sickness (nausea/vomiting peaking with hormone surges), extreme fatigue, and heightened emotional changes, though some experience severe symptoms like hyperemesis gravidarum (HG) requiring medical attention, while others face discomforts in later pregnancy.
According to medical research, childbirth pain actually ranks around fifth on the scale of physical pain. There are several conditions that cause even more excruciating pain than labor, including kidney stones, third-degree burns, and trigeminal neuralgia...
Common pregnancy symptoms like morning sickness and fatigue are often experienced during this time. Second Trimester (Weeks 13-27): The second trimester is often considered the most comfortable. You'll likely experience fewer symptoms from the first trimester and feel more energised.
For many expectant mothers, the second trimester is the easiest three months of pregnancy. It is full of new and exciting milestones for you and your baby. However, despite leaving behind morning sickness and food aversions, some new pregnancy symptoms will begin to take their place.
Doctors advise that during the early stages of pregnancy, it's generally okay to sleep on your stomach, but once you reach 16-18 weeks you should aim to change positions and stop stomach sleeping [8].
For most people, the extreme fatigue of the first trimester is soon forgotten. That's because the second trimester often comes with a glow and a boost in energy. So don't worry if it seems like all you're doing these first few weeks is lying around, dozing, or napping. This is normal.
For example, you shouldn't clean a litter box due to the risk of toxoplasmosis. You should also avoid lying on your back for extended periods of time. At nighttime, sleep on your side instead of your back, as this is best for your circulation. Don't stress if you wake up and find yourself on your back.
Chromosome conditions
If your baby inherits a chromosome condition, they'll not be able to develop properly. This causes a miscarriage. It's not possible to tell which parent passed on the chromosome condition. Chromosome conditions are thought to be the most common cause of an early miscarriage.
The risk of miscarriage also decreases significantly—to about 5 percent—after your doctor detects a heartbeat. This typically occurs at around your 6 to 8 week mark. The chances of having a second miscarriage after a woman has already experienced one is also very slim at less than 3 percent.
A pregnancy may also be more likely to end in miscarriage if you:
