Explanation:

DURING THE AGE OF PUBERTY , THE GIRLS ATTAIN MENSURATION

AFTER THIS THE OVULE PRODUCE ONE EGG EACH MONTH

AND DURING THIS PERIOD THE WALLS OF UTEREUS BECOME SOFT AND SPONGY AND THE FEMALE REPRODUCTIVE SYSTEM IS READY FOR A FERTILISATION

BUT IF THE FERTILISATION DOES NOT OCCUR THEN THE WALLS ARE BROKEN AND COME OUT FROM THE BODY

THEY COME THROUGH WITH THE BLOOD
