period poops :(

period-poops-:(

on my period rn all of a sudden got diarrhea since my first day ystd, along with nausea and a migraine. this is my first time experiencing these kind of symptoms, usually its constipation and vomiting for me but never diarrhea. how long will this diarrhea last and does anyone have home remedies that works fast? very desperate rn cause i have a flight early morning and worried about this diarrhea ughh feels like i have to shit every few mins none of my family members understand my frustration rn

edit: i went to the clinic early morning bc i need anti diarrheal meds and the WOMAN doctor said i dont need it and i just needed to lose weight. made me so mad. and she only gave me ibuprofen.
