Darlin, Do you think that a GP would have prescribed to you if he thought it would cause harm or have affect on your un -baby? You are now past 24 weeks and antibiotics - if needed - are to help YOU. Your immue system needs to be protected, and in doing so, the baby will be also. If you are not 100% happy about it ettelloc, sure ask the Chemist or contact the Pre-Natal Clinic and see what they have to say. Main thing is for yourself at present, don't be getting yourself stressed out worrying about it! All will be fine pet!
