TWW- Testing for BFP

Hey everyone I’m currently in my two week wait! Prey for me haha.

I ovulated either Monday or Tuesday week just gone and I’m due for period 6th of feb

I’d be currently 5-6 DPO

I’m not thinking about testing now but I currently have 2 FRER and 20 internet cheapies. I’m not wanting to buy anymore so I’m wondering when I should test with which tests. I know I definitely want to use a FRER one day before my due period. I’m wondering when I would be able to use the internet cheapies (25mu/i) wjere it should be detectable and when I should use my other FRER???
