Should I test again?

Rachel • TTC #1 since January `14! Hoping for a BFP, but trusting in my Lord to provide in His timing! He is good-- all the time!
Im now cd 33 of who knows how long.... Should I test for pregnancy again after 2 BFNs last week?
​I am not temping so I don't know if I've dropped in temp or if I officially ovulated this month or not.  
​I'm planning on going in vitex ASAP and trying natural/ herbal route . I'm not ready to be officially medically infertile yet ... And hoping that natural herbal things will help regulate and help me ovulate !
​If af doesn't arrive by Friday (cd 36 ) I'll test I think
​Just wondering what others would do
