Is this normal?

Okay. So I posted a post about me bleeding in the middle of my cycle. So my period was AuG. 25. And I bled 6-7 of sept. And now I just started bleeding AGAIN last night...(15 of sept.) And I bled all day today. I notice I started bleeding after intercourse last night. But is it normal for me to bleed ALL day the next day...?? And how much is too much blood? We didn't have really rough sex. Not rough enough to be bleeding like this....I just am getting kinda worried. Should I make a doctors appt. Because idk if its normal and every time I turn around I am bleeding or spotting...and tbh I'm tired of it ruining my pretty panties. Lol jk but need a little advice plz...
