Started getting sick last night, ended up sleeping for 21 hours. I only woke up to throw up or go to the bathroom. 99% sure I have a double ear infection and the flu. Tried waiting it out today since I have my anatomy scan and glucose test tomorrow morning. Really wish I could of went to a walk in clinic because I’m miserable 😩 I hope not being able to keep anything down doesn’t throw off my glucose test.
