She looks healthy, don't stress it. But if you look at how tall she is compared to how few leaves you have, you can tell she stretched real hard. But it seems the stem thickened up enough to make her stand tall and pretty. But I agree with mr blu, just bury her up to her cotelydon leaves when you transplant or even just top dress it to give her extra support (put more soil on top of what you have). What lighting do you have? Bring it in closer to avoid her being all spindly and tall. Gotta be sure she grows proportionally to avoid her wanting to fall over. But she looks pretty dude, keep at it. Read and educate yourself, there is a lot to know. Good luck!
