Went to the doctor yesterday and was told I have the flu. The doctor however, said he's not a fan of prescribing any medication to pregnant women and sent me home. He told me to get rest and take Tylenol. Wtf is Tylenol going to do??? I've been seriously sick for like 4 days now and can't breathe, eat, sleep or function.
