While on you have a yeast, can you get pregnant??

Me, and my partner have been trying to get pregnant for a while now. We haven't been getting pregnant lately. I have gotten a yeast infection. My cycle was suppose to happen. But for the whole cycle, it was only 6 drops. No more period. I took a pregnancy test, and I didn't see nothing what is going on with my body. I need some advice, and help¿???
