i was due for my AF on the 30th. i was on depo for only two shots and was suppose to get another may 2010 but didnt. i got my AF back on November 2010, again dec 30th2010, and then this month i thought i may be preg b.c. we tried while i was suppose to be ovulating. but my AF came the 25th of jan....early. now im having a bad heavy flow. have to change my tampon like 2 times in an hour...and i have clots. sorry if thats TMI. but im wondering could this be an early miscarriage? or is it maybe just my body catching up afte rthe depo? eventhough ive already had 2 AF's b4 this one???
