Could a yeast infection be an early sign of pregnancy (sorry if this is a tmi question)?

I am not a woman who really ever gets yeast infections. in fact ive only had 3 in my entire life. 1st one was right before i found out i was prego with my 2.5 yr old 2nd one was right after i had her and the 3rd now.......my lmp started on the 2nd of this month and ended on the 6th. and then on the 8th i had some spotting which is sooo odd for me bc once af ends shes done until she shows up again for the next month, my next af is due a couple of days from now. ive had no signs of her showing up. so what im wondering is has anyone else had this happen to them? and if so how long was it before you got your bfp. so could a yeast infection be an early sign of pregnancy since i dont get them normally. (When i used monitstat for the first time i read in the insert that if youve never had one or dont get them very often that you may be preg) thanks
