Pain when going to the loo Sunday and Monday. Doctors on Tuesday confirmed urine infection and prescribed Amoxicillin. Wednesday and Thursday got worse and pain like period pain and what felt like a stitch, generally felt unwell, doctors on phone and midwife said I hadnt given amoxicillin long enough. Back to doctors Friday and infection was worse, amoxicillin hadn't touch it. Prescribed Nitrofurantoin. Now feeling awful, feel sick, weak, hot and cold, headache, struggling to eat. 17 weeks pregnant and really struggling. Can anyone advise please?
