Okay guys so last night I was happy one second and the next I started crying cuz my fiancé pulled over to put a dip in . I was like this the rest of the night . I even started crying when my dog laied with me and when I seen a baby on tv .. also every food is making me sick except salt and vinegar chips and orange juice

This let may be tmi but last night my fiancé and I were having sex and he started to touch my boobs and I told him to stop cuz they were super sensitive.. am I letting this get to my head or could I really be pregnant?? What do you guys think
