im 18 years old, recently had sex. its common for me to have regular amounts of discharge and ive learned it may be because my body is naturally heated. recently the discharge has reached a new level but i wasnt worried because it is summer and i my temperature would naturally increase except after just having sex, there was i found blood mixed in as well but after cleaning it, it wasnt continuous but came back one more time throughout the day and went away again. should i be worried about a pregnancy? i show no other early symptoms of pregnancy but im still scared about it. please help
