Strep throat. I start the antibiotics?

35 year old healthy female, 5'6'" 120 lbs, tested positive for strep last week (Wednesday), sore throat and slightly swollen lymphs, fever highest at 98.8 (normally at 97.6) . Went to pick up antibiotics but was feeling better, decided to rest for the afternoon and get retested the following day, retested positive for strep the following day, was going to start antibiotics but started to feel much better. Rested over the weekend and no longer have pain or swelling or fever. So, do I need to take the antibiotics? It's my understanding that any complications from strep would be if my condition was getting worse not improving. I don't want to be reckless, but I haven't taken antibiotics in over 15 years and they upset my digestive system greatly. In summery, should I start the antibiotics? also, breastfeeding
