Am I just having an abnormal cycle ?

Took plan b a few weeks ago, and it made my period early by like 3 days, so I’m here now with my current scheduled period, but I have had no signs of my period ( I usually spot bleed before hand)

I take all precautionary measures, I took plan b just bc I’m not playing with any possible pregnancy, condoms (which broke) were used, and other uses of bc, how long should I wait for my period to come before testing?

Does plan b mess your cycle up?

Just FYI I’m not on any hormonal bc, such as pill, implants and of the like, I have tried them and my body really is sensitive to what I put in it.
