Need help and advice!

Hey there for whoever is reading this, my name is Kaydance and thank u for taking the time to read my concerns. I found out I’m going to be a first time mommy! Im super scared but kind of excited to see how this goes. I am working a full time job and I’m 7 weeks in. I need help with knowing what I need to get for my baby and the best cheapest products for him or her. It is too early to find out the gender unless you guys know any ways of finding out sooner! I just need help with what to expect and how to take care of them as best to my ability. Im turning 20 in September which is pretty young to be having a kid but now I have a life depending on me! For anyone who has been pregnant before, is it ok to get tattooed during pregnancy? On a side note I’m going to prepare way ahead to of time and start buying diapers and baby shampoo ect. What are the best products? Open for recommendations!!
