Heat cycles (estrus) can be unpredictable in some individuals. We usually see some type of schedule unique to that individual, but others are as regular as the seasons. The missed heat cycle may have been a "silent heat", the cycle occurred but the evidence was not obvious. Of course, there may be an underlying cause to suppress cycling, and this would need to be addressed before breeding occurs. Discuss this concern with your veterinarian.

As to stillbirth and developmental anomalies, they can be caused by a multitude of things: infection, drugs, environmental elements (toxins, etc.), genetics et al. Unfortunately, I don't have a simple answer for you. Close monitoring by you and your veterinarian over the next few months may aid with an answer.
