Thanks for posting,
from your description you are most likely having pharyngitis
in pregnancy (inflammation/infection of the pharynx) and most often it can also affect the tonsils (when they are red and swollen), but that could only be confirmed on physical examination. So it is possible you are having tonsillo-pharyngitis. If your cough and fever have subsided it means treatment with amoxicillin
is working. What you need at home now is probably take analgesic (if you feel pain) and do warm water salt gargles to clear off the soreness. Betadine gargles can also help.
or oropharyngitis is not dangerous during pregnancy. But if you develop a high fever
, then it is possible that it can induce abdominal cramps which can lead to a miscarriage
(but that is in very very rare situations). But since you obviously are getting better, I do not feel you should be worried or stressed out. You do not need to go back to your GP except you just want more reassurance.
Hope this helps
