Pregnancy Calculators and Health Tools

Free tools from Eva WomanCare Clinic, Vashi. Every one of them is built around what a gynaecologist would actually tell you, not just the arithmetic.

These calculators are here to answer the questions that come up between appointments: when am I most likely to conceive, when is this baby due, is my weight affecting my cycle, do my symptoms add up to PCOS. Each one explains what the numbers mean, where the method stops being reliable, and when it is worth booking a consultation instead. Nothing you enter is stored or sent anywhere. More tools are being added, including a nutrition calculator, a pregnancy diet guide and a symptom checker.

Which one do I need?

A quick guide if you are not sure where to start.

I am trying to conceive

Start with the ovulation calculator to find your fertile window, and track it against the physical signs listed on that page for two or three cycles. If you have been trying for twelve months, or six months if you are over 35, book a consultation rather than another cycle of guessing.

I have just found out I am pregnant

Use the due date calculator, then book a dating scan between 11 and 14 weeks. The scan is more accurate than any calculation and sets the timing for everything that follows, including the anomaly scan and screening bloods.

My periods are irregular

Take the PCOS assessment first, since irregular cycles are the symptom that most often brings women in. Bear in mind thyroid problems and raised prolactin produce the same picture, which is why the next step is bloods rather than a diagnosis.

I want to know if my weight is a problem

The BMI calculator uses the Indian cut-offs, which sit lower than the international ones for good reason. If it puts you above 23, the useful follow-up is a fasting glucose and a lipid profile rather than a diet.

A calculator cannot examine you

These tools work from averages. Your body works from your own hormones, history and anatomy. If something here has raised a question, one consultation with the right bloods and a scan will answer it properly. Dr. Grishma Ranjangaonkar has over 15 years of experience in gynaecology, fertility and high-risk obstetrics.

Questions about these tools

Yes, all of them, with no sign-up and no email required. Nothing you type is stored, transmitted or shared. Everything is worked out in your own browser.

The arithmetic is exact, but the assumptions behind it are averages. The due date calculator assumes ovulation on day 14 of a regular cycle; the ovulation calculator assumes a fixed luteal phase. Where a method stops being reliable, each page says so plainly, and each one tells you what to use instead.

No, and none of them is meant to. A calculator cannot examine you, measure a hormone or look at an ovary. Use them to arrive at an appointment better informed, with dates and symptoms written down, which genuinely does change the quality of the conversation.

No. There is no database behind these tools and no analytics attached to what you type. The calculations run entirely in your browser, and closing the page clears everything.

A nutrition calculator, a pregnancy diet guide, a meal planner, a baby growth chart and a symptom checker are in progress. They will appear on this page as they go live.
