I started taking Robitussin yesterday (5 days before I'm due to ovulate). I'm intending to take 10mls 4 x daily until after ovulation has happened. However today I have been feeling very nauseous with mild stomach pains and a headache. Has anyone else experienced these as side effects from Robitussin? I'm not sure if I'm sickening for something or if it's the medicine! Sadly I'm definitely not pregnant so that's not the reason for the nausea <img src="">
