Baby gear advice needed please!!

Deidra
So I will be 17 weeks tomorrow and I am curious about when it is appropriate or when I should start buying baby gear. 
I have been buying little outfits and things but when should I start getting the necessities. I don't think I am going to get much from my baby showers so I want to be ahead of the game and make sure my little lady has what she needs when she arrives. I also don't want to go crazy and do things tooo quickly. HELP!!! 
When did you guys start getting the things you knew you would need???
Thanks in advance for the advise!!! 😁😁
