Early wake ups are killing me

Please help. Nothing I do is making my daughter sleep in longer. Everyday for the last month pretty much she’s waking for the day between 3:30-4:30 and I am exhausted. She goes to bed at 7pm because she is so tired, so I can’t even try putting her to bed later.

I’ve tried changing bedtime, capping naps, leaving her to cry for a while when she wakes but she gets so worked up if I don’t go into her.

I try putting her in bed with us when she wakes to see if she goes back to sleep but no.

Tried sitting in her room in the dark with her but she screams and squirms her way out of my arms reaching for the door.

I know some kids are just early risers but this is ridiculous. She’s 19 months. I don’t think she’s teething as she doesn’t have her usual teething symptoms.

Please someone help me or advise me.
