worries

So recently I got a yeast infection due to being on antibiotics and I've never had one...ever and then I noticed I'm super bloated and my fiancé has been saying that I've been super picky about food and stuff...I still have about a week till my period starts and none of these are normal symptoms to my period, but today when I put my menostat in it was slightly bloody and when I wipe it is slightly pink...idk if this is because of the yeast infection or if I could be pregnant because both are current possibilities
