I would be extremely grateful for any help and advice that can be given. Okay so about 4 days ago i came down with what i thought was just a standard cold (constant runny nose) and i get a few of these a year so i didn't worry too much and just carried on with what i would normally do, which involved a shopping trip on Saturday, but then during the day i started coughing and then bringing up phlegm. By the time i was on the train home i began having real difficulty breathing and it honestly felt like i was having an asthma attack (something that i have not suffered with since being a teenager) When we got home my husband rang the NHS helpline for advice which resulted in them calling an ambulance so the paramedics came out to check me out and then take me to hospital. At the hospital i saw a doctor whom informed me that i have a chest infection which was then setting off asthma issues that had been latent since my teens and so he prescribed me Erythromycin (2 250mg tabs 4 times a day) plus an inhaler. He would of prescribed Penicillin he said but i am allergic and according to him Erythromycin is safe to take whilst being pregnant (i am 17 weeks + 4 days) Now yesterday i began having stomach cramps that have gotten worse today, and i know that stomach issues can be a side effect of the antibiotics so i have called my doctors and am just awaiting a call back from a doctor... So i have been worried anyway about taking antibiotics whilst pregnant but now i am even more worried because if the tablets are making me feel this bad then can they harm the baby? I am really scared because even though this baby was unplanned it is now very much wanted and loved and i cannot stand the thought of having another miscarriage... Has anybody experienced anything like this and had a happy and healthy baby at the end of it?
