Well I've lost my girls before 24weeks so I just tell them to wait that's just me giving then advice 12 weeks is early so many people have lost their babys at 12 weeks and onwards
A lot of people will say wait for a few more weeks due to miscarriage but I say go when you're ready. Get the bigger stuff you can afford first then clothes when you know what you're having. That's what I did and now at 34weeks I'm pretty much set thru the end of the year after she comes
Yh I would wait until 20 weeks its to early to shoo now good luck hun
I would wait till you at least know the gender, but also if you are having a baby shower you will most likely get most the stuff you need.
