The challenge of converting from weeks to months during pregnancy
I was recently talking to my friend, who is pregnant, and I asked the classic curious question: “How many months along are you?” Her response was, “I’m 33 weeks.” Instantly, a confused expression came over my face. I kept thinking: “Wow… How many months does that correspond to?” I confess that, as much as I wanted to do the math right away, the math got me confused and I only found out how many months later... I was even embarrassed to ask!
This moment made me realize how common it is to feel a little lost when it comes to counting time during pregnancy. After all, it's not every day that we come across tables of weeks and months. And to make matters worse, I thought about the situation of mothers who, even counting the weeks carefully, end up losing count of how many months that represents.
If you're looking for the quick answer, I'll tell you right away: 33 weeks corresponds to the 2nd week of the 8th month. In other words, the baby is almost out of the oven.

Importance of calculating gestational age
To do this, we created this blog talking about calculating gestational age! It plays a crucial role in prenatal care. We will explore the two main approaches to this calculation and how they influence the understanding of the gestation period.
How to Calculate Gestational Age?
Calculation methods: LMP and embryo size at the first ultrasound
Two main approaches are used to calculate gestational age: from the Date of Last Menstruation (LMP) and the size of the embryo at the first ultrasound. Let's analyze how each method contributes to the accuracy of the calculation.

- Date of Last Menstruation (LMP): This is the most common method. It calculates gestational age from the first day of the last menstrual period. The average pregnancy lasts about 40 weeks or 280 days from the first day of the last menstrual period.
- Ultrasound Method: Ultrasonography is an important tool for evaluating fetal development. At the first ultrasound, usually performed in the first weeks of pregnancy, the size of the embryo or fetus can be measured to determine the gestational age more accurately.
Whether or not to include the first week of the menstrual cycle?
Even if ovulation occurs halfway through the menstrual cycle, the first week is already considered in the week count. Discover how this inclusion impacts the perception of gestation time, especially when pregnancy is identified shortly after a missed period. Exams carried out after a missed period may indicate a gestational age greater than the time since conception.
33 Weeks: How Many Months Does It Count?
The gestational table as a guide
To answer the common question, “33 weeks is how many months?”, we present the gestational table. It serves as an essential guide for converting weeks to months or trimesters during pregnancy.
Quarter | Weeks | Months |
---|---|---|
1st | 02-06 | 1 |
1st | 07-10 | 2 |
1st | 11-14 | 3 |
2nd | 15-18 | 4 |
2nd | 19-23 | 5 |
2nd | 24-28 | 6 |
3rd | 29-33 | 7 |
3rd | 34-37 | 8 |
3rd | 38-42 | 9 |
Meaning of the Probable Date of Birth (DPP)
The probable due date (PPD) marks the point at which the pregnancy reaches 40 weeks. However, birth is considered full-term, that is, it occurs at the appropriate time, when it occurs between 37 and 42 weeks.
Special Care in Elective Caesarean Section
In cases of elective cesarean sections, it is vital to understand the right time for the procedure. Studies indicate that babies born between 37 and 39 weeks may not be fully ready. Experts recommend scheduling cesarean sections after 39 weeks. Always consult a doctor.
