Thinking about starting a family? Whether you’re considering traditional approaches or assisted reproductive technology, there’s a lot to learn. And a lot of misconceptions. Here’s a quick but thoughtful look at some common pregnancy myths, and what the facts actually say.
1. Pregnancy is not exactly nine months long
The idea that pregnancy lasts nine months is only roughly true. Medically, a full-term pregnancy is measured as 40 weeks, or 280 days, from the first day of your last menstrual period. But that’s not the same as nine calendar months. And most pregnancies don’t follow an exact schedule. Full-term typically means anything from 37 to 42 weeks, which means most babies arrive a little early or a little late — and that’s completely normal.
2. You might not know you’re pregnant right away
Many people assume pregnancy symptoms show up immediately. In reality, early signs like fatigue, mild cramping, or nausea are easy to miss or mistake for something else. And depending on your cycle length or how you conceived, it might take a while before a missed period or positive test confirms it. In most cases, pregnancy isn’t visible on ultrasound until at least five to six weeks, even with close monitoring.
3. Your due date is just an estimate
Due dates are useful, but they are not precise. They are calculated based on the first day of your last period and assume a textbook 28-day cycle with ovulation on day 14. That works as a baseline, but ovulation and implantation vary widely — especially if you’re going through IVF. Only about 5 percent of babies are actually born on their due date. Most arrive within a window of about two weeks before or after.
4. You will likely gain weight during pregnancy
Weight gain during pregnancy is not just expected, it’s necessary. Most people gain somewhere between 25 and 35 pounds, but that number depends on your starting point and health profile. The key is gaining steadily and at a healthy pace, which supports your baby’s development and helps reduce risk. Your provider can help you understand what’s right for your body and your pregnancy.
5. Cravings are common, even if we don’t fully understand them
Cravings during pregnancy are real, though the science behind them is still a bit murky. Some people think cravings reflect nutritional needs, but there’s little strong evidence for that. It’s more likely that hormonal changes — and a heightened sense of smell and taste — are driving the sudden desire for citrus, cereal, or something salty. As long as you’re eating safely and in moderation, it’s fine to follow your cravings. Just be sure to talk to your provider if you ever crave non-food items, which could signal something more serious.
6. Mood swings are normal and not your fault
Hormones affect more than your body — they impact your mood and emotions too. Many people experience mood swings during pregnancy, especially in the first and third trimesters. You might feel anxious, irritated, weepy, or just overwhelmed. That’s common. But if your emotional state starts to feel unmanageable or persistent, talk to someone. Mental health during pregnancy matters just as much as physical health, and support is available.
7. Taking care of yourself is not optional
Pregnancy is not just about growing a baby — it’s about supporting your own health so you can do that well. That means more rest, more hydration, balanced meals, and whatever kind of movement feels safe and sustainable. Whether your pregnancy is natural, medicated, or after IVF, self-care is not indulgent. It’s part of prenatal care.
We hope this short list helped clear up a few misconceptions and made pregnancy feel a little less mysterious. If you’re thinking about starting your own journey, Life IVF is here to support you.
