what do i do ???

Sjala

after 2 months of no period and feeling many symptoms.i went to my local hospital all the did was a pregnancy test which came back negative . however it still doesn't explain the pressure on the right side of my stomach. the extreme nausea I've had or the apparent mood swings . I've set appointments for the obgyn to do a second opinion . I just need to know everyone's thoughts on the situation.
