Malunga nale Calculator
A period calculator predicts when your next several periods are due from the first day of your last period and your average cycle length. Counting forward one cycle length gives each period start; ovulation falls about 14 days before the next period, and the fertile window is the five days before ovulation plus the day itself. It also lays out a schedule of upcoming cycles with their period, ovulation and fertile dates.
On a 28-day cycle, your next period is due 28 days after the last one began, the one after that at 56 days, and so on for as many cycles as you ask it to show. Ovulation for each cycle is placed 14 days before that period start, with the fertile window running the five days before it. Enter a longer or shorter average and every projected date shifts by the same amount.
Use it to know when to expect your period over the coming months, to plan around it, or to see your fertile days alongside each cycle. Set your usual period length so the schedule shows start and end dates. Real cycles vary by a few days month to month with stress, illness and hormones, so the predictions are estimates; a consistently missed period is worth a pregnancy test or a clinician’s advice.
Imibuzo ebuza rhoqo
Uyiqonda njani ukuba xa ndiza kuphuma iinyanga ndiza kuphuma njani?
Ixesha ngalinye lixesha elipheleleyo emva kokuqala, ngoko ke isixhobo sidibanisa ixesha lakho elipheleleyo (iintsuku ezili-28 ngokungagqibekanga) kumhla wokuqala wexesha lakho lokugqibela, kwaye siphindaphinda ukuba sibonise iinyanga ezininzi ezilandelayo.
Ichanekile kangakanani inkqubo yokuqikelela ixesha lokukhulelwa?
Icinga ukuba ijikelezo lihlala lide. Ijikelezo elinyanzelekileyo litshintsha ngeentsuku ezimbalwa ukusuka kunyaka ukuya kunyaka—kwaye litshintsha kakhulu xa kukho umthwalo, ukugula okanye utshintsho lweehormone—ke ngoko sebenzisa umhla womhla njengoluvo olungaqinisekiswanga.
Yintoni ukuba umjikelo wam awuhambelani?
Ngenisa umlinganiselo wakho wobude bexesha lokukhulelwa ukuze ubone ukuba linjani, kodwa ulindeleko luya kuba luncinci. Ukulandelela ixesha lokukhulelwa okanye ukusebenzisa isixhobo sokukhulelwa kukunika umfanekiso ocacileyo kunekhalenda ethe nkqo yobude.
Uzakuqala nini umjikelo wam olandelayo?
Ixesha elipheleleyo lixesha elipheleleyo emva kokuba unyaka wakho wokugqibela uqale, ngoko ke kwixesha elipheleleyo leentsuku ezili-28 ixesha lakho elilandelayo lilindeleke ukuba liqale iintsuku ezili-28 emva kokuba unyaka wakho odlulileyo uqale. Isixhobo sibonisa iinyanga ezininzi ezizayo usebenzisa umlinganiselo wonyaka opheleleyo oza kuwufaka.
Ndiyicwangcisa njani ixesha eliphakathi lokukhulelwa?
Log the first day of each period for a few months, then average the gaps between them. Entering that average gives more accurate predictions than assuming a fixed 28-day cycle.
Ingaba le sixhobo sibonisa imihla yam ephilileyo?
Ewe. Kufutshane nexesha ngalinye elilindelekileyo libonisa umhla olindeleke ukuba ukhulelwe, malunga neentsuku ezili-14 ngaphambi kokuba uqale ukhulelwe, kunye nemini esithandathu yefestile yokukhula ephelelwe lixesha.
