Any help ladies ? Pls ?

So I have been sorta spotting like this since the 19th up until today ... I had protected sex on the 22nd but my concern is the condom kept falling off and he just kept putting it back on & kept going, although he never got to finish but Ik Precum is still a thing, what do y’all think .. also the spotting has never happened to me a week after my period ... what could that be ??
