Does spotting reduce the effectiveness of birth control pills? Can excessively intense intercourse affect the occurrence of spotting?

Hello, I have a question because today I got a slight spotting and tomorrow I'm just starting a week placebo. My stomach hurts slightly as if for bleeding. Yesterday I had intercourse with a condom but it is possible that the penetration could be too intense, is it possible that the abrasions in the middle of the vagina resulted in spotting the next day? This is my fourth pack of pills, I know that there is spotting in the first months of contraception, but I'm not sure if everything is fine and if contraception works according to use, I take them all according to the application. The previous bleeding occurred normally, very stressed please answer. Best regards
