Blood when im not on my period?

So should i be concerned if i have light bleeding my period ended like from january 7th to the 11th and i had sex the day after my period and the day after that and also on the 10th day of my cycle..i think he went alittle rough with fingering but im not sure..i was somewhat dry while he fingered me...should i be concerned? My fertile starts in 3 days and ovulation is happening later on so idk..if i should be worrying or not because it could be a tear...but its weird because he had sex already before.. 😣 help me..
