I have a bladder infection after unprotexted sex . could i be pregnant? i know he came in me alittle but i'm bleeding heavy now. it's been 5 days now.

Possible: It is possible that you are pregnant any time you have had unprotected intercourse and it is also possible that you have gotten a sexually transmitted disease. As you are bleeding heavily the second (STD) is more likely. To know for sure check a pregnancy test and repeat it in 3-5 days if it is negative. If the heavy bleeding continues you need to see your doctor for testing. Be safe from now on.
