Ovulation will stop, your mare will no longer tease "in" to a gelding or stallion. Best way to tell is through palpation by an equine veterinarian. Most changes are not noticeable until late in the pregnancy, when the belly will show movement, and the foal positions into the birth canal. Right before birth a bag will form, containing colostrum.
