Randomly feel off ?

Al

Anyone randomly start feeling weird (heart palpitations , feeling weak, suddenly sweating , shaky, fatigued ) this is about the 3rd time this has happened to me . I haven’t been able to see my OB yet she’s booked out till Oct 24 so I haven’t been seen yet . I don’t want to switch drs seeing as my dr is an absolute angel great at her job and has delivered my other 2 kids . Just wondering if anyone else has felt this way or if I should maybe visit the ER
