For anyone who has had Group B Strep

Did you have the antibiotics and did they cause you and your lil one to develope thrush, making it difficult to breast feed? I really want to breast feed. I just found out yesterday I was GBS positive 😔 I wish I could avoid the antibiotics somehow, but I just want a healthy happy baby. Just looking for others that have had this experience... I'm so upset. My pregnancy has gone so smooth. Literally I feel like I haven't even changed besides my belly and some back and hip pain lately.. I've felt great the whole time. No sickness ever. Never had heartburn. All the testing has come back negative until now. :( I knew something was bound to not go in my favor... this sucks. I feel completely helpless.
