Ok here is my story....
I was tested 1/31/11 for all vaginal infections and tested negative for everything.
I am pregnant and at my first prenatal exam (3/3/11),a month later, I tested positive for chlamydia. I really think that something is not right.
I had sex with my boyfriend once ( two weeks after the first test) in between the two dates and the nurse said that I must have contracted the infection on that date.
I told my boyfriend about it and he says that has not cheated on me and that he knows that i haven't cheated so the test must me wrong. I believe that he has not cheated on me, it is not in his character. I don't believe that in between 1/31 and 2/11 that he has sex with another girl contracted chlamydia and the gave it to me. I also have not been with anyone else.
Also at my prenatal exam i tested positive for BV and a yeast infection. I am wondering if there was some kind of mix up. I went to get a second test done from a different doctor to be sure. I have to wait 7 days for the results though

.
My boyfriend will also get tested, but will have to wait until Monday now. I really don't know what to think right now. I am sure he was faithful, I am 100% sure I was ,faithful, and I am really shocked about having a negative result and then having a positive result 4 weeks later.
I guess I don't really have a question other than has anyone had a false positive of some kind of mix up? Also I want to make this thread so that when I add updates that it might help someone else in the future.
I have been researching and found threads on message boards with women claiming that were positive and then negative with the second test. I hope this will be the case with me.
Anyway, thanks for reading.
