In brief: Subungual

Hematoma or blood under the nail is a possibility.
Splinter hemorrage is also possibility. Melanoma can present this way but fact yu have it on both big nails would render this possibility as less likely.

In brief: Trauma

Usually is caused by toe hitting end of shoe.
See podiatrist to be sure.
