Pregnancy tests, due dates, pediatric dosing, vaccine schedules, and child growth calculators. Browse our free pregnancy & pediatric tools below — all calculators are instant, accurate, and require no sign-up.
Clomid Ovulation Calculator — Estimate ovulation timing, fertile-window timing, and cycle milestones when taking Clomid (clomiphene citrate).
Birth Control Cost Calculator — Compare the total cost of birth control methods over time. Factor in insurance coverage, copays, and method effectiveness for informed contraception decisions.
False Negative Pregnancy Test Calculator — Estimate how timing, test sensitivity, and urine concentration can affect the chance of a false negative pregnancy test, and when repeat testing may add useful context.
Ireland Vaccine Queue Estimator — Estimate your position in a vaccine rollout queue using Ireland-style priority groups. Adjust population, supply rate, and priority tiers to model any campaign.
Pediatric Maintenance Fluids Calculator — Calculate IV maintenance fluid rates for children using the Holliday-Segar (4-2-1) method. Includes dehydration correction and electrolyte requirements.
Pediatric GFR Calculator — Estimate glomerular filtration rate in children using Schwartz, Counahan-Barratt, and CKiD formulas. Includes CKD staging and age-specific normal ranges.
Positive Pregnancy Test Calculator — After a positive pregnancy test, estimate gestational age, hCG projections, due date, and key pregnancy milestones based on DPO and hCG levels.
Pediatric Blood Product Worksheet — Estimate pediatric blood-product volumes for pRBCs, platelets, FFP, cryoprecipitate, and whole blood, with blood-volume context and reference infusion rates.
Pregnancy Test at 3 Weeks Calculator — Estimate how likely a pregnancy test is to detect pregnancy at about 3 weeks from the last menstrual period. Frames very-early testing with implantation timing, hCG levels, and test sensitivity.
Pregnancy Test Calculator — Estimate when a pregnancy test is more or less likely to detect pregnancy based on DPO, cycle timing, and test type. Compare general home, early, and blood-test timing context.
Stillbirth Risk Assessment Calculator — Review stillbirth-related risk factors in a simplified educational worksheet that compares selected factors with broad population baseline rates.
Urine Pregnancy Test Calculator — Compare home pregnancy test brands by sensitivity and cost, and factor in urine concentration, hold time, and read window as timing and sensitivity reference points.
Vaccine Strategy Calculator — Model vaccine distribution strategies: compare dosing approaches, estimate rollout timelines, and analyze supply constraints for any population and vaccine.
Vaccine Immunity Duration Calculator — Estimate how long vaccine immunity lasts: model antibody decay, T-cell memory, and booster timing based on vaccine type, age, and immunological factors.
Vaccine Production Calculator — Model vaccine manufacturing capacity and timelines: compare platforms (mRNA, viral vector, inactivated), estimate ramp-up, costs, and cold chain requirements.
