Pregnancy Weight Gain Guide
Many women search “how much weight should I gain during pregnancy”. Healthy weight gain is different for every mother. It depends on pre-pregnancy weight, height, baby growth, health condition and doctor advice.
Weight gain may be small in the first 12 weeks. Some mothers may not gain much because of nausea or vomiting.
Weight usually increases slowly as appetite improves and baby growth becomes clearer.
Baby gains more weight in the final months, so regular doctor visits and growth monitoring are important.
Do not follow random diet plans during pregnancy. Ask your doctor about safe weight gain, especially if you have diabetes, thyroid, BP or twin pregnancy.

Pregnancy, Fertility & Scans - Frequently Asked Questions
1How many days after my period can I get pregnant?
Many women are fertile around 10 to 14 days after the first day of their last period, but this changes with cycle length. If your cycle is short, ovulation may happen earlier.
2Can I get pregnant immediately after my period?
Yes, it is possible, especially if you have a short cycle or early ovulation. Sperm can also stay alive inside the body for a few days.
3Can I get pregnant before ovulation?
Yes. The days before ovulation are important because sperm can survive for a few days. That is why the fertile window usually includes the days before ovulation.

Some women notice tiredness, mild cramps, breast tenderness, smell sensitivity or mood changes before a missed period. But these signs can also happen before periods.

It gives an estimated date only. Your doctor may change the due date after ultrasound scan, especially in early pregnancy.
9How many weeks pregnant am I?
Pregnancy weeks are usually counted from the first day of your last menstrual period, not from the exact conception date.

The best time is usually the fertile window, which includes a few days before ovulation and the ovulation day.
