Okay so last month my period was a week late an more painful than its ever been. It lasted for the normal 4 days. I went to the gyno and she didnt seem too concerned about my period being late. Fast forward some, to now. I'm suppose to get my period next week, but I experienced it early, this week. It lasted for 1 day and was very heavy bleeding. I have taken 3 plan Bs this cycle, not because I had unprotected sex but because I'm just a paranoid person and took it in addition to spermicide condom. My doc did put me on birth control to help with extreme cramping but I haven't started it yet so it can't be the cause of irregularity. I'm 21 years old and want to know if I should be concerned and schedule another appointment with gyno? I feel silly since I just saw her but I'm concerned. My period normally lasts 4 days and is a 24 day cycle. I have lost weight and have been fighting a head cold for a while now-no fever tho. Any help would be appreciated!
