Indlela yekhalenda yokuvikelwa ekukhulelweni yenziwa ngo-1920 yiJena Jnologist Ogino no-Austrian Knaus. Le ndlela isekelwe ekubaleni usuku olulinganisiwe lokuvuthwa nokuzigwema ekuziphatheni ngokocansi ezinsukwini ezivundile kakhulu zokukhulelwe. Indlela yekhalenda ingenye yezinto ezingathembeki kakhulu. Kusuka ku-9 kuya ku-40% yabesifazane abasebenzisa le ndlela bakhulelwe. Ngakho-ke, indlela yekhalenda ephakeme kakhulu yokuvikelwa yasungulwa - indlela yokubonisa. Ngaphezu kokubala usuku lokuvuthwa kwegazi, kuthatha isimo somzimba wesifazane.
Indlela yekhalenda ye-Ogino-Knows
Le ndlela yindlela enhle kunazo zonke yokuvikela. It isekelwe kuphela ekuboneni kanye nokubala. Ngenxa yokungaqondakali okukhulu emisebenzini yemvelo yomzimba, indlela yekhalenda yindlela kuphela yokuvikelwa eyamukelwa yiSonto LamaRoma Katolika.
Okuyinhloko yendlela kanje. Ngemuva kokulala ngokobulili ngaphakathi kwesifazane, i-spermatozoa iphila kuphela amahora ambalwa. Futhi ukufika emlonyeni wesibeletho basuke besebenza kusukela ezinsukwini ezimbili kuya kwesonto. I-Ovum ekwenzeni i-ovulation (ephuma e-ovary) ingafakwa kuphela ngaphakathi kwamahora angu-24. Ukwazi ukuqala kwe-ovulation, ungahlela ukuhlanganyela ocansini ukuze ngisho nangokwemvelo ungavumeli ukukhulelwa okungadingeki. Ukuze usebenzise ngempumelelo indlela yekhalenda ye-Ogino-Knaus, kubalulekile ukugcwalisa ikhalenda yemijikelezo yokuya esikhathini sonke unyaka. Noma kunjalo, le ndlela ifanele kuphela kwabesifazane abanomjikelezo ovamile wokuya esikhathini. Ukuhluleka okuncane kakhulu ohlelweni lwe-hormonal, ukugula, ukwethuka kwesibindi kungashintsha umjikelezo wesimeni futhi kuholele amaphutha ekubaleni. Futhi, ngenxa yalokho - ukukhulelwa.
Ngendlela ka-Ogino-Knaus, ungakwazi ukubala "izinsuku eziyingozi" (ezithandekayo zokukhulelwa):
- Ukuqala kwesikhathi "esiyingozi" (esivundile) kubalwa ngendlela: ubude bomjikelezo omfushane buyizinsuku ezingu-18;
- Ukuphela kwenkathi evundile kubalwa ifomula: ubude bomjikelezo omude kunayo yonke izinsuku ezingu-11.
Isibonelo, ukubuka imijikelezo engu-12 yokugcina, ubale ukuthi umjikelezo omfushane kunemihla engama-26, kanti isikhathi eside kunazo zonke izinsuku ezingu-32. Kuvela ukuthi kusukela ezinsukwini ezingu-8 (26-18) kuya ezinsukwini ezingu-21 (32-11) zomjikelezo (futhi usuku lokuqala lomjikelezo kuthathwa njengosuku lokuqala lokuya esikhathini) yizona ezihle kakhulu ukukhulelwa. Uma umgomo kuphephile kusukela ekukhulelwe, ngalezi zinsuku kubalulekile ukugwema izenzo zobulili, noma ukuvikelwa ngezinye izindlela. Futhi ngokuphambene, kusukela ezinsukwini ezingu-1 kuya kwezingu-8, futhi kusukela ezinsukwini ezingu-21 kuze kube sekupheleni komjikelezo, le ndlela ayikwazi ukuvikelwa.
Ukuvikelwa le ndlela akuyona engcono kakhulu. Kodwa ngokuhlela kokukhulelwa le ndlela iphumelela kakhulu.
Indlela yekhalenda ye-Symptomatic
Kuyaziwa ukuthi ngomjikelezo wezinsuku ezingu-28, ukuvuthwa kwenzeka ngosuku lweshumi nane lwenyanga yokuya esikhathini. Kodwa lokhu kuyinani elilinganiselwe. Kwabaningi besifazane, lo mjikelezo uhlukile, futhi ukuvota kubonakala kancane kancane noma kamuva. Ngokucabangela ukungaphumeleli kokuvikelwa ekukhulelweni ku-Ogino-Knaus, ochwepheshe batusa ukufaka usuku lokuvotela ekhalendeni ngeemingcele eminye emithathu. Okokuqala ukulawula ukushisa komzimba (izinga lokushisa). Owesibili ukulawula isimo se-mucus yomlomo wesibeletho esivela esibelethweni (indlela yomlomo wesibeletho). Okwesithathu ukulawula ushintsho esikhundleni somlomo wesibeletho, ukuthobeka nokuvuleka kwayo. Imiphumela yalokho konke okubonwayo kubhalwe ekhalendeni elikhethekile, ngokusho ukuthi yiziphi izinsuku eziphephile zobulili eziqunyiwe.
Ukusebenza kwendlela yekhalenda ephawulekayo kuyinto ephakeme kakhulu. Yesibili kuphela ukugcwalisa inzalo. Ngokusetshenziswa kahle, abesifazane abangu-3 kuphela ku-1000 banokukhulelwa okungakahleleki (0.3%!). Lokhu kufana nendlela ye-hormonal futhi iphakeme kakhulu kunezinye izindlela zokuvimbela ukukhulelwa. Kodwa-ke, le ndlela ayivikeli izifo zobulili. Ukuze kusetshenziswe ngokuphumelelayo indlela ebonisa uphawu, kubalulekile ukuqapha isimo sakho nsuku zonke. Ukubheka kuthatha imizuzu engaba ngu-10 ngosuku. Ekuqaleni kubonakala kunzima futhi ngaphambi kokusebenza kwayo kunconywa ukuba uqeqeshe ngokusebenzayo.
