I need help , I recently missed my period last month and I'm not on birth control . I've had lower abdominal pains & also gas pains really bad gas , sometimes diarrhea & sometimes constipation . My boobs are very sensitive and I've been feeling very nauseous . I've been craving certain foods but then when I smell it it makes me nauseous . My stomach feels very weird idk how to explain it . I'm very bloated . I've had frequent headaches . I've been very tired and emotional and crabby . Am I pregnant ?
