How many days should I wait to start teasing again? She was last bred on the 1st of May?

You can have her checked via ultrasound at 15 - 18 days after she stops standing for the stallion. That's about the point that she may be coming into season again. Although, coming back into season may not mean she's not bred. Some mares show heat even when they are bred and if they are covered, it will cause them to lose the pregnancy. Having a vet check via ultrasound is just about the safest way to go.

Only if the cervix is penetrated - as in A.I. procedures-would the pregnancy be lost. In natural cover, the stallion's penis does not penetrate the cervix so the pregnancy would not be lost.

Incorrect. In natural cover the penis may penetrate the cervix. It is in fact fairly common for the penis to penetrate into the uterus to some extent during regular breeding cycles as the cervix is dramatically relaxed when under the influence of estrogen during estrus.

Penetration of the cervix if live covering a pregnant mare is less likely, as the cervix is tightly closed. The irritation of the cervix as a result of the breeding however may cause prostagladin release, which is turn can cause the pregnancy loss.

In other words, breeding a pregnant mare live cover may result in pregnancy loss, just as breeding her AI may.

Ok, but if the mare started "Showing heat" on the 1st and was OUT (no longer accepting the stallion) on the 7th, when can I reasonably expect her to start to show some signs of returning into season.(Stallion is on site) I will not cover her again until she is in standing heat and shows no PG on the ultrasound.

I would estimate that she could start showing signs of heat on the 21st., give or take a day or 2. Most mares cycle approximately every 21 days during the summer. This can change based on the mare's history and the time of year. Earlier in the spring and later in the fall their cycles may be longer and more erratic.

Ok, I am confused now. This mare just came back in, and we bred her this morning? It has only been 14 days since she was last bred?? She stood for the stallion on the 1st and would have nothing to do with him on the 2nd. Now she is in standing heat again??? Is this normal?

Right on the money. The entire estrous cycle duration (from ovulation to ovulation) in the mare is 21 days - about 14-16 days diestrus, and 5-7 days estrus ("heat").

Check out the article available here for more details.

Note that some mares may be already in foal, and yet demonstrate "heat" and accept a stallion. They are few and far between, but do exist, so pregnancy checking her with ultrasound is valuable.

Additionally, if the mare just came back into heat, there was no need to breed her the first day. Most mares ovulate in the last 24-48 hours of their standing heat, so the normal procedure is to wait until the third day before breeding for the first time, and then breed every other day until the mare will not tease to the stallion. Breeding more often than every other day can cause inflammatory response problems in the uterus and reduce the chances of pregnancy.
