 [ Symptoms ] my bf and i had sex 228 got period 31 it came early i feel crampy and have back pain coukd i be pegnant [ Disease ] the most common reason for this is a foreign body usually food your three year old for some reason decided it was a good idea to put a green bean pea or in the nose if there is a bad smell and a nasty drainage from just one side this is the most likely reason nasal foreign bodies can be challenging to remove so it may be a good idea to allow the medical provider to do it for you
