Enye indlela yokuhlela umndeni ukuvimbela ukukhulelwa ngokusebenzisa ikhalenda. Le ndlela iqala ngeqiniso lokuthi owesifazane kumele abale usuku olulindelekile lokuvuthwa futhi abale ukulala ngokocansi ngezinsuku, izinsuku ezifanele kakhulu zokukhulelwa. Lezi zinsuku zibizwa ngokuthi yisikhathi sokuzala futhi zinsuku eziyisikhombisa ngaphambi kokuqala kwe-ovulation, kanye nosuku olulandelayo.
Indlela yokuvikela ikhalenda ingenye yezinkinga zokuvimbela inzalo ezithembeke kakhulu. Kunezinye izindlela eziningi ongavimbela ukubonakala kokukhulelwa, kodwa izindlela zemvelo ziphephile. I-Spermatozoa ingaphila emasendini amahora ambalwa, futhi emlonyeni wesibeletho "bayakwazi ukwelula" cishe izinsuku ezintathu, ngezinye izikhathi ngesonto. Ngemuva kokushiya i-ovary amahora angu-24, iqanda lingakhulelwa.
Ukuvikelwa okulungile ekukhulelweni ekhalendeni kubalulekile ukucubungula umjikelezo wenyanga ezinyangeni eziyishumi nambili. Kodwa kwabesifazane abanenkinga yokunga esikhathini ngokungavamile le ndlela ayisebenzi.
Indlela yokubala ukuvimbela kokukhulelwa ngekhalenda?
Ukubala okulungile kwezinsuku lapho ungakhulelwa khona, kukhona ifomula ethile:
- Isikhathi esivundile silingana nobude bomjikelezo omfushane, zingakapheli izinsuku eziyishumi nesishiyagalolunye.
- Ukuphela kwenkathi evundile kulingana nobude bomjikelezo omfishane, izinsuku ezingamatshumi ayishumi nanye.
Isibonelo, ngokubhekwa kwemijikelezo eyishumi nambili, okuncane kunayo yonke unyaka izinsuku ezingu-26. Umjikelezo omude kunazo zonke izinsuku ezingamashumi amathathu nambili. Ngakho-ke, izinsuku ezinhle kakhulu zokukhulelwa ingane zingukuhamba komjikelezo ukusuka kwesishiyagalombili kuya kwezingamashumi amabili nanye. Ngakho-ke, ukuze uvikele ekukhuliseni, kungcono ukuhlala kude nocansi noma ukusebenzisa amakhondomu nezinye izindlela zokuvimbela ukukhulelwa. Kusukela ezinsukwini ezingu-21 futhi kusukela ekuqaleni kuya kwesishiyagalombili inombolo ayikwazi ukuvikelwa.
Ukuvimbela Ukukhulelwa Kwemvelo
Kuze kube manje, izindlela zemvelo zokuvikela ziphephile kunazo zonke empilweni yabesifazane, ngenxa yokuthi zithandwa kakhulu. Kodwa ngokuvikelwa okunjalo kukhona ukungaphumeleli, ngenxa yokuthi yiziphi izindlela ezingenakwenzeka eminye imibhangqwana.
Ukuvikelwa kwemvelo kunezinzuzo eziningi:
- ukuphepha kwezempilo;
- ukungabikho kwemiphumela emibi;
- ukuhileleka ekusebenzeni kokubili abashade;
- ukuthuthukisa ubudlelwane bomndeni;
- ukuntuleka kwezindleko zezimali.
Ngendlela, i-ovulation enembile inganqunywa ngosizo lwenqubo ephawulekayo. Le ndlela iwuphawu lokushintsha kwezinga lokushisa komgogodla, kanye nokuhambisana kwemisipha yomlomo wesibeletho.
