Hello I am a 20 year old woman and I have missed my period. I don't know why it is late. I haven't been sexually active for about three months and I came on my period last month but I went to the doctor after I got off my period last month and was given some medicating for a yeast infection. I have also been having repeated yeast infection every month for the past 6 months. I'm not sure what is wrong can someone help me? My period is about two weeks late. :confused:
