I have had my period twice last month and for about a week now I have been feeling fatigued, increased appetite and libido, nausea bloating. Today I started to have lower back pain and a headache could I b pregnant? I have no problem using the restroom however when I kay down at night it hurts to lay on my tummy and sensitive when eating

I suggest you take an HPT with first morning urine and if that doesn't work, have a test done at your doctor's office. Some of the symptoms you describe would not occur unless you were maybe 3 or 4 months pregnant.
