I'm 19 weeks pregnant and doctor has told me I have a UTI and has put me on antibiotics for 7 days I'm only on day 2 of the antibiotics but feel like my symptoms are getting worse day by day I'm in so much pain in my back, my tummy and lower abdomen, constant headache and nauseous all the time I know that antibiotics take a while to work but I'm a bit worried because I've never felt so ill before and just wondered if anyone has any advice or has been through this before?
