We had unprotected sex on 11 September, my fiance took unwanted 72 after 5-6 hours. She had her period on time i.e on 21 September but on first day blood colour was different than normal but on second day it seemed normal. Her next period came very early one week before and it lasts only two days with light bleeding. She felt sick by having high fever with joint pain and from couple of days she vomits everything wt ever she is consuming. Red rashes have appeared on her body with itching. Is there any chances of pregnancy or this vomiting is due to high fever and itching. She is under treatment, she has taken lot of antibiotics like tobramycin, ceftriaxone, cefexine and also stereiod Methylprednisole. Kindly explain
