Not sure what to think

[Rachael2681]

Hello everyone. Im brand new to this while on birthcontroll my periods never come. Off it they regulate. I d/c my bc April 2016 got my period May 1-3 (when I do get my period its only about 3 days) Not sure if or when I ovulate took a few home tests they always came back neg. Today is 12 days before I should get my next period. Think I have a yeast infection(was also on antibiotics for 7 days for dental work) so thats may explain that. Today my nipples have been extreamly sore which has never happened to me (tender breasts yes, never nipples though). Slight cramping here and there. Been very emotional (BF and I have been fighting this past week) I know this is a ton of info but do you think its just hormones or has anything like this happens
to anyone and turn out to be a positive pregnancy?
