The Use of the Yellow Stamps or = Symbols
The plain yellow stamp is used to record discharge:
Before ovulation: to record the Basic Infertile
Pattern (BIP) of discharge
After ovulation: to record any discharge, including
seminal fluid from day 4 past Peak until menstruation.
Think in patterns!
It is incorrect to judge fertility or infertility by an isolated
specimen of discharge. It depends on where the woman is in the hormonal
pattern of her cycle.
The BIP
For some women the BIP is dry. Some women never experience dry days
but always notice some slight discharge at the vulva. A BIP of discharge
is recognised by its unchanging pattern. This unchanging pattern
reflects the unchanging nature of hormones when there is no cervical
activity. Any change alerts the woman to the change in the BIP and
to apply Early Day Rule 3.
Regular Cycles – less than 35 days
Observation of three cycles of unchanging discharge in the BIP is
recommended in order to determine accurately the point of change
to potential fertility.
In the first cycle any discharge apart from bleeding is recorded
with white stamps or the 0 symbol. A review of this cycle may indicate
the BIP for this woman is one of discharge as she has no dry days.
In subsequent cycles this unchanging pattern is recorded with the
plain yellow stamp or = symbol. Three cycles of discharge without
intercourse over the time of the BIP will confirm the BIP and the
first point of change.
Cycles of less than 35 days will have one BIP, either dry or unchanging
discharge.
Delayed Ovulation – Cycle longer than 35 days
The BIP of discharge can be confirmed by observing an unchanging
pattern for two weeks, without intercourse and in the absence of
bleeding. During these two weeks of charting the white stamp or
0 symbol is used to record any discharge apart from bleeding. A
review of the chart will reveal the unchanging pattern and the unchanging
discharge is then recorded with plain yellow stamps and the Early
Day Rules applied.
When ovulation is delayed there may be a combined BIP:
Dry and / or
Discharge
