Last time I was intimate was Nov. 28th. Took a morning after next day and got my period. Getting my periods sin e then but seems a little lighter than usual. My breasts were sore on and off for a while but not any more. Recently did two pregnancy tests that were Negative. No symptoms at all. Just feel bloated. If I do counted from the last day I had intercourse I should be almost 3 months pregnant. Should I be worried and is there a possibility to be pregnant?
