I'm 19 years old and have had alot of ear problems lately. In the past month I have been on 2 sets of prescription steroids to help with my ear problems. My last period was November 27 (during one of the steriods) and my menstration is very irregular. It is always atleast more then 34 days between periods. but now its only been 3 weeks since i got off my period and i have been bleeding ever so lightly. mostly brownish. I did have unprotected sex with my boyfriend the day i got off my period, but i'm almost positive its not because i'm pregnant but i'm not ruling that out. Any ideas??
