Hi, I'm preggers with my 3rb baba and after my blood test results being positive my doc sent off my wee for testing. Counting by last period I'm nearly 7 weeks and have my dating scan today late arvo. Anyways, my wee results came back with bladder infection which I think is UTI? I got given antibiotics which is Cefalexin Sandoz 500 MG to take 4 times a day. Is it safe? I'm worried. Never had to take anything during both my pregnancies with both my boys.
