So a condom broke with me and my boyfriend in the beginning of October and at the end of October I had an abnormally light period. Over the last few weeks I have been experiencing nausea on and off everyday for the last week or two, I can't eat some of the foods I love because they just taste horrible, I have been extremely moody and irritable, I have been very tired all the time, and my sense of smell has been crazy the last few days. I took two pregnancy tests and they both came up negative. Could I still be pregnant and if not what is wrong with me?
