The good answer is : I called her this morning.
⓵ Direct speach repeats, or quotes, the exact words spoken.
Example: When I called her thi morning she said, "I'm not feeling so good."
⓶ Indirect speach is normally used to talk about the past, so we normally change the tense of the words spoken.
Example: When I called her this morning, she said that she wasn't feeling so good.
→ Your sentence is indirect!
There you go! I really hope this helped, if there's anything just let me know!☻
