When I got swabs took before my hsg I tested positive for group strep b. The hospital have asked my doctor to treat me with antibiotics but I'm a little confused. I tested positive for this when I was pregnant with my daughter 5 year ago n i had the antibiotics during labour. I'm confused as to why I have to take antibiotics when I'm not even pregnant and I'm worried that the antibiotics will affect the chlomid that I'm due to start this weekend. Advice please anyone?!
