well im 16years old and i've been on depo for 2years since March 06. im use to spotting when its time to go get my next shot(which is irritating)..well i've missed 3weeks of my depo and hve had intercourse with my boyfriend about 6times since i've been off. now i've been spotting even more (darker than usual), urinating and eating more. i don't if i could be pregnant or not but i took a test 2days after the last time me and my boyfriend had intercourse. i took the test(it was negative) because i just got a pap smear 3days ago. my next appointment is to switch my depo over to the implant(july 14)..but with these syptoms im a little worried..i need help..and answers NOW!! someone please help :'( .
