This ovulation calculator helps as an ovulation predictor, determining your most fertile days of the month. Menstrual periods differ from woman to woman and month to month. Use this calculator as an ovulation calendar to help determine when does ovulation occur, the timing of your ovulation, and peak fertility.
This ovulation calculator estimates the ovulation date and the corresponding due date if the pregnancy is according to normal biological cycles. It is not suggested for avoiding pregnancy, based on ovulation calculation.
Ovulation is the process by which a mature ovarian follicle ruptures and discharges one or a few eggs during a female’s menstrual cycle. This process is controlled by the brain through the release of the luteinizing hormone or LH and the follicle-stimulating hormone or FSH. If the egg is fertilized by the sperm, it may implant from 6 to 12 days later and then pregnancy starts.
Fourteen days before the first day of your next period is the average ovulation time. Yet, the ovulation calendar fertile days may differ among women. Hence, just basing it on cycle length is not a dependable variable for your ovulation day. Ovulation tests are more precise, with a 99% precision rate, and they can be bought without prescription.
Typically, ovulation test kits measure the LH level in urine. A high amount of the LH level, otherwise known as a positive test result means the start of the ovulation and fertilization windows, which happen during the next three days.
The regular menstrual cycle is between 28 to 32 days. Some women have shorter or longer cycles, so the exact timing of ovulation can differ. Here is an overview of a usual 28-day menstrual cycle.
Your cycle starts on the first day of blood flow.
Days 2-14 – Follicular Phase
The follicles on your ovary become active and your cervical mucus begins to thin.
Ovulation starts mid-cycle, but can differ between Day 11 and Day 21 of a woman’s cycle. Increasing estrogen levels trigger the LH surge, which causes the follicle to ovulate and release an egg. It is important to graph your basal body temperature and LH surge so you know when you ovulate.
Days 15-22 – Luteal Phase
After releasing the egg, the follicle releases progesterone. This thickens the lining of the uterus for implantation.
Days 23 to 24
Implantation of a fertilized egg can occur. At this stage, hormones released during pregnancy can be detected through a pregnancy test.
Days 25 to 28
If pregnancy does not happen, your hormone levels will fall. The uterine lining sheds, which results in your period.
Some of the signs of ovulation are:
• Abdominal bloating
• Cervical mucus or vaginal discharge may look clearer, thinner, and stretchy
• Higher levels of LH, luteinizing hormone, measured through a home urine test
• Light spotting
• Slight increase in basal body temperature, usually 1/2 to 1 degree, measured by a thermometer
• Slight pain or ache on one side of the abdomen
• Tender breasts
Your odds of getting pregnant become higher when you have sex 1 to 2 days before you ovulate. However, cycles differ in length and some women are irregular or have miscalculated their cycle. Sperm can also survive in a woman’s body for up to 5 days. To improve your chances, have sex frequently beginning 3 days before ovulation, continuing until 2 to 3 days after you think you have ovulated.
You should give the sperm a chance to swim upstream before going to the bathroom. Stay in bed for at least a few minutes after sex.
Avoid vaginal sprays, scented tampons, artificial lubricants, and douching. This can alter the normal acidity of the vagina and make it an inhospitable environment for the sperm.
Graph your basal body temperature and your cervical mucus. You might also utilize an over-the-counter ovulation predictor kit or OPK to check for hormonal changes in your urine before ovulation.
Try yoga, meditation, or long walks to lower your stress. Research shows that stress can interfere with pregnancy. There is no need to quit your job or change your life. Simple acts such as exercising, journal writing, or holding hands with your spouse can decrease stress.
Research shows that weighing too little or too much can disrupt ovulation and may also impact the production of key reproductive hormones. A healthy BMI is between 18.5 and 24.9.
If you are trying for a boy or a girl, there is no sure, natural way to choose the sex of your baby. But with the help of this ovulation calculator boy or girl can be a bit easier. Nevertheless, note that the male sperm swim and expire faster than female sperms. To get a boy, have sex around 12 hours before you ovulate or as close to ovulation as possible. This is so the male sperm will be there when the egg drops. To get a girl, have sex several days before ovulation, so more female sperm will be there when the egg drops. Nonetheless, experts say your odds are 50-50 unless you use a sperm-sorting technique after artificial insemination.
