need answers asap.

I usually have a normal cycle and I always bleed at least 2 days even though I'm on birth control. lately I've been tired, irritable, always hungry, back pain, little nausea and migraines like crazy. all of this stuff is very new to me, except the back pain. I haven't had any bleeding for about 4-1/2 weeks and my "period" before was only a day and a half long. I am on a low dose birth control; and I need as much input as possible on this situation. I would really like to know if this is a possible pregnancy. (especially women who have/are pregnant, I would really love your input) thanks.

so i know you said you took a prego test and it was negative,  but i just wanted to say that my friend got prego twice on the low dose birth control... she aborted the first and didnt expect that it could happen twice...she has now switched to an implanted BC, but back to your situation, the best thing you can do is wait a few days and test again.. make sure you are eating and living healthy and take either a daily vitamin or you could take prenatal vitamins if that would ease you mind more just incase cause if you are prego you body need the extra vitamins
