Malunga nale khadi
A conception calculator estimates when conception likely occurred. From a due date it counts back 266 days (38 weeks), because fertilization happens about two weeks after the last period on a standard 28-day cycle and pregnancy runs 280 days from that period. From a last-period date it counts forward to ovulation (cycle length minus 14 days). Because sperm survive several days, a likely conception range is shown around the central date.
Working from a due date, subtract 266 days: a due date of, say, 40 weeks out places conception 38 weeks earlier, with the last period roughly two weeks before that (due date minus 280 days). Working from your last period, it adds cycle length minus 14 to find ovulation — day 14 on a 28-day cycle, day 16 on a 30-day cycle. It then shows today’s gestational age, measured from the last period rather than conception.
Use it to trace back roughly when a pregnancy began, either out of curiosity or to line up dates with a due date. The several-day range reflects that sperm can survive up to about five days, so conception may follow intercourse by a few days. Actual ovulation varies, so an early dating ultrasound is the most reliable check; this tool is for information, not medical advice.
Imibuzo ebuzwa kaningi
Ukuthola ingane kulinganiselwa kanjani kusuka kusuku lokuzalwa?
Usuku lokuzalwa luyizinsuku ezingama-280 (amaviki angama-40) ngemuva kosuku lokuzalwa oludlule, futhi ukukhulelwa kwenzeka cishe ngezinsuku ezingama-14 ngemuva kosuku lokuzalwa. Ngakho-ke ukukhulelwa kungakapheli usuku lokuzalwa oluncane lwezinsuku ezingama-266 (amaviki angama-38).
Kungani isigaba sokukhulelwa sibonisa, hhayi usuku olulodwa?
I-sperm ingahlala isikhathi esingaphezu kwezinsuku eziyisithupha esigabeni sokukhula, ngakho-ke ukuxhumana ngesondo nsuku ezimbalwa ngaphambi kokukhulelwa kungadala ukukhulelwa. Ubukhulu buhlanganisa ifasitela elikhulayo elingase libhekene nezinsuku zokukhulelwa.
Ingabe usuku lokukhulelwa lufana nosuku lokuqhathaniswa?
Akudingeki. Ukukhulelwa (ukubeletha) kwenzeka lapho i-sperm ihlangana ne-egg ngesikhathi sokuya esikhathini, okungahle kube zinsuku ezimbalwa ngemuva kokuxhumana. Ukulinganiselwa kubhekisa ekukhulelweni, isikhathi sokuqala sokuphila.
Ngiyithola kanjani ingane uma ngizi ukuthi ngizokhulelwa nini?
Khubaza izinsuku ezingama-266 (izinsuku eziyi-38) kusukela kusuku oluzoqala. Ngenxa yokuthi ukhulelwe uqala ngezinsuku ezingama-280 kusukela kusikhathi sokugcina futhi ukhulelwe ngezinsuku eziyi-14 ngemuva kwalokho, ukhulelwe uqala ngezinsuku ezimbili ngemuva kosuku oluzoqala.
Ingabe i-calculator yokukhulelwa ingamitshela ukuthi ngubani ubaba?
Kuyinto elula. Inikeza usuku lokukhulelwa olunokwenzeka kanye newindow yezinsuku eziningi ebhekene nokukhulelwa, kodwa ngenxa yokuthi amaseli omntwana ahlala ephila izinsuku eziningi, ubaba akakwazi ukuxazululwa kusuka kusuku olulodwa futhi adinga ukuhlolwa kwe-DNA.
Kungani ukhulelwa ngemuva kwezinsuku ezimbili zokuqala zonyaka?
Ukhulelwe kubhekwa kusukela ngosuku lokuqala lwesikhathi sokugcina ukuze kube lula, kodwa ukubeletha kwenzeka ngesikhathi sokukhulelwa cishe amaviki amabili ngemuva. Lokhu kusho ukuthi ubudala bebele le thuluzi libonisa ukuthi kungakapheli amaviki amabili ngaphezulu kwesikhathi kusukela ekukhulelweni.
