I got my BC on Jan. 8th & my period was supposed to come on Jan. 15th though nothing came that day. so at 10pm that night i took the BC.. It is 4 days later and still nothing. I do have a mild yeast infection that is on and off the past few days, mild cramping, a craving for chocolate, and a little bit of nausea here and there. any advice?

UPDATE

I just wiped after going pee and this was there. any idea what this may be?

UPDATE Now 5 days late... took a hpt today and this is the result i got. looks negative to me :(
