Is it the penicillan

Ap

Everything has been going great with baby and she started sleeping better to where she'd make a few noises at night and i'd put my boob in her mouth and she'd go back to sleep, well Thursday I went to the doctor because I got strep throat, I got prescribe penicillan and was told to keep breastfeeding well Friday I was up from 12-5am with her crying like colic symtoms, Saturday was the same and today is the 3rd time. Nothing has changed in my diet or routine. Could it be the penicillan affecting her? I still have 6 days of doses left to take.
