My Girlfriend Took Unwanted 72 An Within 5 Days She

My girlfriend took unwanted 72 an within 5 days she said she was bleeding I thought it was side effect but now she is bleeding again exactly on her period date and she is saying it was not how she feels earlier when she get mens..is it normal or it is something to be serious about..(earlier she used to have pain on lower stomach during period and now no pain)
