I am a first time breeder and we are live covering. I bred my mare on 4-9/4-10/ 4-11 and 4-15 on 4-16 she showed no signs of being in heat. Now on 4-22 when she is by the stallion she squats and urinates. Could she be back in heat? and do some mares still show when they are not in heat?

Most mares ovulate in the last 24-48 hours of standing heat. As you bred her on the 9,10,11 and 15, and on the 16th she did not stand, you may have missed the optimum breeding time, which would have been somewhere between the 11th and 15th. Incidentally, you reduce your chances of achieving pregnancy by breeding every day - every other day starting on the third day of standing heat is sufficient with normally fertile stallions.
Having said that, yes, some mares will indeed show estrus (heat) even though they are pregnant.
I would have your veterinarian perform an ultrasound examination. That will be definitive for you. Breeding her again (if she stands) if she is pregnant may cause pregnancy loss.
