Tests for ovulation

Test of Ovulation

In a regularly menstruating woman with a 28 days cycle, ovulation occurs on day 14 of the cycle (The first day of menstruation is considered Day 1 of cycle). However, ovulation occurs at different times even in the same woman. There are several changes that occur during menstruation which can indicate that a woman is ovulating.

CHANGE IN BODY TEMPERATURE
A basal body temperature can be taken daily. When there is a slight increase in temperature of 0.5 degrees Celcius, this may indicate ovulation.
1
CHANGES IN THE CERVICAL MUCUS
During ovulation due to the oestrogenization, the mucus discharge from the vagina will becomes more watery and cupious. The vagina may feel more slippery because of this mucus.
2
SLIGHT PAIN MAY BE FELT DURING OVULATION
This is due to the rupture of the Graffian follicle. Te pain may be felt on either side of the lower abdomen, which indicate the site of the ovary where ovulation occurs. Usually this alternates between the right and left side.
3
SLIGHT PER VAGINAL BLEEDING
During ovulation some women may have slight bleeding.
4
URINE LH (LUTEINIZATION HORMONE) TEST
During ovulation the LH rises and this can be picked up by a urine LH test. However, since the rise in the LH only lasts a few hours, the LH test must be tested several days before the expected date of ovulation so that it will not be missed.
5
TRANSVAGINAL ULTRASOUND
Serial transvaginal ultrasound can be performed from a few days before the expected day of ovulation to determine when is the expected day of ovulation. Graffian follicles can be seen easily during this ultrasound and when they reach about 18 mm ovulation is expected to occur.
