Justme,
HI*5...
Fau,
I ever read a book.. I remembered tat the most fertile days is 7th to 10th days after menses.. and also a few days b4 ur next menses dates..
Dont "put" there if dun want bb... "put" more if u want to hv bb...haha..
The other method is look at ur muscus..(hope i spelled correctly).. thin, transparent n elastic one is said to be fertile..
I can only roughly remember only...
