For the Prega News Pregnancy Test Kit, the most accurate results are typically obtained using morning urine, as it contains higher levels of the pregnancy hormone hCG (human chorionic gonadotropin). However, you can still test in the afternoon, but the results may be less reliable if the urine is more diluted. It’s best to test with your first morning urine for the most accurate results. If testing in the afternoon, try to avoid drinking large amounts of fluids before testing, as this can dilute the urine.

Late periods can happen due to stress, hormonal changes, thyroid problems, weight changes, travel, illness, polycystic ovary syndrome or other underlying medical conditions, but pregnancy is also possible if her period was due on the 20th and it is now the 27th with no bleeding. A home urine pregnancy test can be taken now and is usually reliable after a missed period, especially when using the first morning urine and following the kit instructions. If the test is negative but the period still does not start, repeat it after 2–3 days or consult a doctor. If she has severe pain, heavy bleeding, dizziness, or unusual symptoms, seek medical care promptly.

Ovulation usually occurs about 12-16 days before the next menstrual period, and the most fertile days are typically around the middle of the cycle. Since your wife’s last periods were on 1 February and 5 March, assuming her cycles are roughly 28-30 days, her likely ovulation would be around 14-18 February and 19-23 March, and the best time for intercourse to increase the chances of pregnancy is during these days and a few days before, having sex every 1-2 days. Keep in mind that cycle lengths can vary, so tracking menstrual cycles, observing ovulation signs like cervical mucus changes, or using ovulation kits can help identify the most fertile days more accurately. Consulting a doctor is also helpful if you plan to conceive or have been trying for some time.
