Maidir leis an áireamhán seo
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.
Ceisteanna Coitianta
Cén chaoi a meastar coincheap ó dháta dlite?
Is é an dáta dlite ná 280 lá (40 seachtaine) tar éis an tréimhse menstrual deireanach, agus tarlaíonn coincheap thart ar 14 lá tar éis an tréimhse sin.Mar sin, is é coincheap thart ar an dáta dlite lúide 266 lá (38 seachtaine).
Cén fáth a bhfuil raon coincheaptha le feiceáil, ní dáta amháin?
Is féidir le sperm maireachtáil suas le thart ar cúig lá sa chonair atáirgthe, mar sin is féidir le caidreamh cúpla lá roimh ovulation a bheith ina chúis le toirchis fós.Tá an raon ag clúdach an fhuinneog thorthúil timpeall an lá ovulation measta.
An bhfuil an dáta coincheap mar an gcéanna leis an dáta caidreamh?
Ní gá. Tarlaíonn coincheap (toirchiú) nuair a bhuaileann sperm an ubh ag ovulation, a d'fhéadfadh a bheith cúpla lá tar éis caidreamh collaí. Díríonn an meastachán ar ovulation, an nóiméad bitheolaíoch coincheap.
Cathain a cheap mé má tá a fhios agam mo dháta dlite?
Dealú 266 lá (38 seachtaine) ón dáta dlite.Toisc go bhfuil an toirchis dáta mar 280 lá ón tréimhse deiridh agus coincheaptha thart ar 14 lá tar éis é, talamh coincheaptha thart ar dhá sheachtain tar éis an tréimhse sin.
An féidir le hiarmhéideoir coincheap a insint dom cé hé an t-athair?
Tugann sé dáta coincheap is dócha agus fuinneog roinnt laethanta timpeall ovulation, ach toisc go maireann sperm roinnt laethanta, ní féidir atharthachta a shocrú ó dhátaí ina n-aonar agus ní mór tástáil DNA.
Cén fáth go bhfuil coincheap thart ar dhá sheachtain tar éis mo thréimhse deiridh?
Tá an toirchis dáta ón gcéad lá den tréimhse dheireanach le haghaidh áise, ach tarlaíonn toirchiú ag ovulation thart ar dhá sheachtain ina dhiaidh sin.Sin é an fáth go léiríonn an aois iompair seo an uirlis seo thart ar dhá sheachtain níos mó ná an t-am ó coincheap.
