discharge

Okay so, I went to get my pap from my doctor, he found a lot of discharge and really claims it be clamydhia . I highly doubt it, haven't had vagina discharge untill I've been pregnant and my boyfriend is totally clean. I haven't been with anyone else in over a year and a half. I know for a fact it's not that. Maybe an infection, but it doesn't itch. It's not sore. I feel totally normal.  Help?
