Home urine pregnancy tests detect the hormone hCG. Most are reliably accurate from the first day of a missed period. Some high‑sensitivity tests can pick up hCG about 8–10 days after ovulation (a few days before a missed period), but early results are less reliable. For best accuracy use first‑morning urine, repeat after a few days if negative, or get a blood test.

Most over-the-counter rapid urine pregnancy tests reliably detect hCG around the day of a missed period (about 14 days after ovulation/conception). Highly sensitive early‑detection tests can sometimes pick up pregnancy about 6–8 days before a missed period—roughly 7–10 days after conception—but accuracy is lower earlier. Repeat testing at the missed period or a quantitative blood hCG test is recommended for confirmation.

Prega News (a urine pregnancy test) is highly reliable but not 100% correct. Accuracy is highest when used after a missed period; testing too early can give false negatives. False positives are uncommon but can occur with some medications, recent miscarriage/abortion, or certain medical conditions. For definitive results, repeat testing or get a quantitative blood hCG test and consult a healthcare provider.

To definitively confirm pregnancy, get a quantitative serum beta‑hCG test and a transvaginal ultrasound. A rising quantitative hCG supports early pregnancy; visualization of an intrauterine gestational sac or fetal heartbeat on ultrasound is definitive. Home urine tests are screening tools; positive results should be confirmed by a clinician who may repeat blood hCG and perform ultrasound to rule out ectopic pregnancy and confirm viability.

Early signs of pregnancy can include a missed period, light implantation spotting and mild cramping, breast tenderness and swelling, fatigue, nausea or "morning sickness", increased urination, food aversions or cravings, bloating, mood swings, and heightened sense of smell. Some women notice these within one to four weeks after conception, but symptoms vary—use a pregnancy test or see a clinician for confirmation.

Pregnancy can often be detected by a blood hCG test about 10 days after conception. Home urine tests usually become reliably positive around the day your period is due—typically about 14 days after ovulation. For maximum certainty, clinicians recommend waiting up to three weeks (about 21 days) after conception or intercourse before relying on a single test result.
