first let me start. by the fact that i have had my period 4 times within the past 2 months. have had unprotected sex inbetween and during on the last period. i havent taken a pregnancy test...but i was reading up on alot about miscarriages....ive had horrible back pains and hip pains, i feel like my breasts are getting larger, and ive been having really bad nausea..

and to top it off... im not even SURE when my next period will be because its been so irregulare.

could this be a miscarriage.. or still a chance of me being preg. or just a really messed up period? please help.
