am i pregnant???

So heres the deal. I had sex with my fiance on jan 21 and the condom broke. i had just gotten off BC so my hormones are all whacked out and i didnt take plan b because i thought there was no way i could be pregnant. well i had my period two days later for a total of 4 days but it was light and not as bad cramp associated with it. usually its horrible. well its now feb 10th and for the past two weeks i have been throwing up sparatically and have been feeling fatigued and having massive headaches and cramps liek that associated with my period. but no bleeding. in these past weeks i have noticed a slight pink color on my TP after using the restroom and also am having a creamy white discharge. Im urinating all the time and im usually a can eat anything kinda girl lately i want sour foods. i dont get sick so the fact that im like this makes me think im preggers. can anyone help me?
