Repeat urine test

Rebecca • Pregnant with baby #2. Have a little girl who is 5 years old.
Hi all. I'm 14 weeks pregnant & on Wednesday i went to the doctors and while I was there she asked if she could have a urine sample, she then told me that I didn't have a urine infection & there is no sugar in my wee. I then receive a letter 2 days later asking for a repeat urine test. I'm worried sick!!!!! Any ideas ?
