Uncertain & Need Help

My period was 8 days late after BF came in me, then I bled heavy black/dark red blood but used 1 pad; changed pad that night at 6p; then red or bright red idk the next day-changed pad at 6a; then bleeding tapered off but changed pad anyway at 6p; & today nothing-same pad. So I bled heavy 1 pad for 1 day & basic next day-1 pad still = 2 days bleeding after period 8 days late??? Oh, & I rec'd. a faint line the day before 2 day bleeding. Breasts stopped hurting on 'heavy' day & they were really heavy & painful. But on this day & starting that night on the 2nd day, they began to tingle around nipple/areola area but no pain??? (Update: now they hurt???) This is my second pregnancy, I have 6yo, & I dont know anything about tingling breasts feeling/sensation. PLEASE HELP. THANKS! Am I still pregnant?
