To get up out of bed in the morning, you can say "I'm getting up" or "I'm waking up." The phrase "getting up" means to rise from a lying down position, while "waking up" means to become alert and active after sleeping. These phrases come from the past participle forms of the verbs "get" and "wake," which are commonly used to describe the act of rising from bed in the morning.

Here are some examples of sentences using these phrases:

"I'm getting up at 7:00 tomorrow morning." (我明天早上7点钟起床。)

"I always have a hard time waking up on Mondays." (我总是很难在周一早上起床。)

"I set my alarm early so I have time to get up, shower, and have breakfast before work." (我把闹钟设早了，这样我就有时间起床、洗澡、吃早餐，然后去上班。)

In general, when talking about waking up or getting up, you can use either phrase interchangeably. However, "waking up" may be used more often when talking about the process of becoming alert and active after sleeping, while "getting up" may be used more often when talking about the physical act of rising from bed.
