Unfortunately, your photos did not come through. I am unable to see the situation. Sometimes, stress or disease can cause it to flower out of season. Other times, a cold snap, then a warm snap will cause them to break dormancy.
As long as it is not disease, then you can expect the plant to continue on as normal in the spring. Here is an article that will offer more information on the plant:
