I am 4 to 5 week post-partum and have just developed a different, bad odor from my vagina. I am no longer bleeding or really having discharge any different from before pregnancy. I do not notice any other symptoms of infection (no fever or otherwise feeling sick.) Not sure if it is a coincidence but it began the day after having intercourse for the first time since giving birth (using a condom.) I am going to call my doctor in the morning, but I am wondering if this could be normal.
