Did you check your histogram before and / or after shooting this image? Everything you'd need to know should have been obvious in the histogram. Either or both the shutterspeed or ISO could have been adjusted. If the ISO was fixed, dial it down to move the histogram to the left. If using Exposure Compensation in Aperture Priority, move the EC dial to the left, letting the camera determine how to lower the exposure.
Finally, look at your metering mode. If you spot metered on the dark center of the flower against a bright(er) background, it was your decision-making that caused the camera to produce this result.
