question for you ladies.

Katie
Hey girls, so I am 1 day away from AF. This is my husband and I's 3rd month trying after losing our 1st baby in October. I remember the first time I got pregnant feeling like I was about to start my period. And if I remember correctly I went 2 weeks before i found out to get treated for a yeast infection. 
For the last couple of days I've had mild itching off and on and a strong sweet type of smell down yonder. I've been slightly crampy on and off. And tonight I noticed I have whitish dried up discharge in my underwear. 
Anybody have any symptoms/signs like this that have been pregnant?
