She had her period on Feb 24th-March 4th. She got sick part way through with cough and congestion. She took Equate for sinus congestion on an empty stomach on the 4th. That same day she started getting really sharp pains and shes had them ever since. She said some days they are light but she can still feel them and other days are really sharp and she can feel them in her stomach and sides. Whats going on here?
