Advice please

I’m curious how many dpo did everyone get there positive? I’m currently one day passed my missed period and still getting bfn’s. This isn’t something abnormal for me as I usually have to take medicine to induce my period but wasn’t sure if I’m out of the running this month and should take my medicine or if I should wait a bit and then take it. Sometimes my period will come on it’s own and I’ve had signs of it coming but nothing yet.
