Advice please!! :)

I've had cm that has a blood tinged pinkish color only when I wipe. It has stopped now and its like sticky (tmi) sorry.. I'm 6 days late for my period but I could have ovulated later than expected. I just started tracking my cycles and could have miscalculated. Ive also been taking amoxicillion for a slight uti. I took a hpt test time morning with fmu and bfn should I wait a couple more days and take another or should I expect af. We have been ttc for about 3 months now.. any advice would be greatly appreciated :)
