Can a Yeast Infection cause you to get a false BFP


So I took to different test yesterday , and they came out positive, I've also took a Saturday that was faint positive, I work at Amazon and I had a little pelvic pain, so came to the ER, they rushed me and said I had a yeast infection , but one nurse said it can't cause a false positive. I asked the doctor for a blood test he basically said no and rushed me out!!
