When should I test ?

I had withdraw bleeding the 5,6,7 of January. I took test on the 26th and it was negative and again the 1st of February . It was negative but I could of swore I saw a FAINT line . But it could have easily been my eyes playing tricks. So I was wondering when I should test again ? I’m trying to no test to much and get my feelings hurt soo what y’all think ? (I also posted pics of my test from the 1st)
