How many weeks pregnant am I?
Same math as the pregnancy-week tool, aimed at the full-sentence search. Results still refuse fruit-size poetry — weeks + days only. Estimate only — not medical advice.
Enter a date to see an estimate.
What this page does
People type the whole question. This landing answers it with the same GA engine: LMP, EDD, or IVF transfer in, weeks and days out, plus a trimester hint.
If you only remember a positive test date, that is not LMP — reverse from an EDD if you have one, or ask the clinic.
When to use
You searched the full sentence; you want leftover days shown, not a round week badge.
When not to
Postpartum + new pregnancy dating belongs with a clinician, not a casual LMP guess.
Assumptions
Browser-only planning arithmetic. Defaults are disclosed on the page. Ultrasound and clinic policy override this tool.
Examples
LMP May 1, 2026 · as-of Jul 17, 2026 → 11 weeks 0 days.
EDD Mar 1, 2027 · as-of Jul 17, 2026 → GA weeks + days from EDD path.
Gotchas
Clinic dating after ultrasound can differ from browser math — the clinic wins for medical decisions.
Wrong input dates (retrieval vs transfer, spotting vs true LMP) slide every result.
Estimate only — not medical advice.
How this is calculated
The math stays in your browser. Enter the dates you actually know, read the estimate, and treat clinic ultrasound dating as the authority when it disagrees.
Nothing here is medical advice, a diagnosis, or a substitute for prenatal care.
