I have been bloated now for nearly 3 weeks. I thought to begin with that my period had come early (they are irregular) as my boobs were quite sensitive and I have been moody, however it wasn't and the moods and bloating have continued. I am on the pill and have been for 5 years, I am not overweight and I am eating healthily. I was diagnosed with PCOS in February and also suffer from GAD. I have felt nauseous & tired & just run down for months but have never been bloated for this long. I have also had sharp pains in the right side of my abdomen since early this morning so I am taking pain killers. I have also noticed in the past week I have been urinating frequently so I bought some over-the-counter treatment for cystitis but this hasn't helped. I am 20 years old. Does anyone have any ideas as to what this is?
