− Keeping a calendar of menses for 6 months – count day one of one cycle to
day one of the next cycle. Add them up and divide the answer by 6 to get the average cycle length. However, if the variation is too great, this calculation will not help. − Observe body signs – at ovulation a woman may feel pain or cramping on the back or abdomen. Menses may come 2 weeks later. − The breasts feel bigger, heavier and lumpy after ovulation and before menses. Mark this change on the calendar and note when menses actually comes. − Headache or backache may be experienced just before menses.

• What to use for the menstrual flow?
∼ Sanitary napkins
These are rectangular pads of cotton layers with plastic outer lining worn inside
the underwear (panties) to collect and absorb the menstrual discharge.
− Change when nearly soaked through.
− Change several times a day to prevent stale odour that occurs when − Wrap used napkins in paper and dispose into a proper disposal bin. − Do not flush used napkins down the toilet.
Tampons are thin rolls of soft cotton pressed together and a string is attached at
the outer end and extends through the vagina and hangs outside the vulva. It is
inserted into the vagina to soak up menstrual discharge. Tampon use does not
harm a virgin woman. Women using tampons are advised to watch out for toxic
shock syndrome (TSS).
− Push tampon into the vagina with an applicator at an angle upwards and
− Pull the string to remove the tampon after use. − Tampons require less changing since there is no odour. − If menstrual discharge is heavy, tampons must be changed frequently. − Swimming becomes more comfortable when using tampons. − Tampons cannot “travel” to other parts of the body since the cervical os − Wrap used tampons in tissue / newspaper and dispose into proper disposal − Do not throw used tampons into the toilet bowl. • Toxic Shock Syndrome
Toxic Shock Syndrome (TSS) was first recognized in children in 1978. In adults it
was found that TSS occurs in menstruating women using very high absorbency
tampons. These hogh absorbency tampons contain polyester foam and
polyacrylate rayon that soak up magnesium from the vaginal discharge. Reduced
magnesium level cause staphylocossus to produce large amount of toxin and
causes TSS. The incidence of TSS is highest on the 4th day of menses when the
menstrual becomes lesser. Certain women have the tendency to be highly
susceptible to this toxin.
∼ Signs and symptoms of TSS:
− Fever (with body temperature above 38.8OC / 102 OF).
− Desquamation (peeling of skin) of palms and soles occurring 1 – 2 weeks − Myalgia (pain in the muscles).
∼ Preventing TSS
− Avoid use of tampons.
• Alternate tampons with sanitary napkins. • Should be monitored for possible recurrence. • Doctor may prescribe antibiotic therapy during subsequent menses to prevent or reduce the possibility of recurrence.
