Should I go to the doctor? Pls help

So for about a little over a month ago I noticed a change in the smell of my vagina. Before it didn't really smell like anything . Ive always been in tune w what it smells like so when it changed I definitely noticed. I started having a lot of discharge all the time it was getting annoying. My period came & went & normally after a period I don't have little to no discharge but it just started right back up. Anyways I don't know if I should go be concerned. I'm not itchy or anything like that it's just discharge all the time. Then a few days ago I had sex & when I went to the bathroom I was bleeding . Not a lot but there was some blood. I don't have any bumps itchyness or anything but now I'm a little scared bc why was I bleeding ...
