Why did my doctor change my due date?
Early ultrasounds are more accurate than LMP. If the baby measures significantly bigger or smaller than expected in the first trimester (usually a difference of >7 days), the doctor will update your due date to match the baby's actual size. This is standard practice.
Can I fly in the third trimester?
Generally, yes, until 36 weeks. However, many airlines require a doctor's note after 28 weeks. It is risky to fly late in pregnancy because if you go into labor, you are away from your care team. Always check with your provider.
How accurate is the gender prediction?
Calculators cannot predict gender. Gender is determined by the sperm (X or Y chromosome) at conception. You can find out via NIPT blood test as early as 10 weeks or via anatomy scan at 20 weeks. 'Old Wives Tales' calculators are for entertainment only.
What if I don't know my LMP?
Don't worry. Your doctor will order a 'dating scan.' They will measure the Crown-Rump Length (CRL) of the embryo. This measurement is extremely accurate in the first trimester and will establish your official due date.
Is it safe to exercise?
For most uncomplicated pregnancies, yes! Exercise helps reduce back pain, prevents excessive weight gain, and may shorten labor. Avoid contact sports or activities with a fall risk (like skiing). Always get clearance from your OB.
When will I feel the baby move?
First-time moms usually feel 'quickening' (flutters) between 18-22 weeks. Second-time moms might feel it as early as 14-16 weeks because they recognize the sensation.
What is a 'Chemical Pregnancy'?
It is a very early miscarriage that happens shortly after implantation, often before a missed period. It accounts for 50-75% of all miscarriages. While emotionally painful, it is usually a sign that you *can* get pregnant.
How many weeks is 9 months?
Pregnancy is actually closer to 10 lunar months (40 weeks). 40 weeks / 4.3 weeks per month = ~9.3 months. This is why doctors use weeks, not months, for accuracy.
Does IVF affect my due date?
IVF dating is more precise than natural dating because the exact moment of fertilization is known. Your due date is fixed based on the transfer date and age of the embryo, and it rarely changes.
What are the signs of labor?
Consistent contractions (getting stronger and closer together), water breaking (gush or trickle), and losing your mucus plug ('bloody show'). If you are unsure, call your labor and delivery unit.
