could i be pregnant??

so the app ive been using shows the flower (the day the egg would released) on 26th of may and my partner and I had protected sex the same day (condom only im not on pill) on the 31st of may i saw small blood spots and was like "im sure im not due yet" checked and was still 9 days away and today have had a very light pink period all day im still 8 days away from my period being due and have cramps but breast are not sore and as im normally super regular i wanted to hear what others think? Ive only ever come 3 days early never 9 days its very usual for me....

update: rest of the evening the light pink almost stop then this morning it was a slight more red on wipe but still light now it has gone really light again with hint of pink its never been enough for being on pad im wearing a light pad but there is nothing on it only when wiping.
