Brown spotting

Today I had brown spotting, my period was Sat (light), Sun (light), Mon (light), Tues (brown spotting) and stopped, I had sex the day before my period started and after it ended 3 times with condoms and it broke but he pulled out, and today I started light pink and brown spotting again. Is this a normal thing ? I never had this happen to me before and we are not TTC reason why we used condoms also we are not on any birth control or anything. Please comment your experiences
