hi, im 18 and iv'e been reading alot of these things on here about trying to figure out if im pregnant..and i don't know if i am or not..my period was like a couple weeks ago, but for the past week iv'e been bleeding like a light color pink . And i also have been feeling different lately ..more sleepy,crampy,and i keep getting this burning feeling that comes up to my throat like im gonna puke..all i do is burp though lol,which is funny cause i never burp. but um im actually on that depo shot and i dont see how i could be pregnant with this shot..the last one i got was may 7th and im going to get the next one aug 4th...can someone help me. i'm like up and awake right now..i cant sleep or get confortable..ugh.
