I have been off my birth control for over 6 months now. Before i was one it for 2 yrs or more, but because of the weight that i had gained from it i decided to stop. It has been 5 weeks now and i have missed my period. I took about 6 pregnacy test and all came out negative. I am really concerned and i would highly appreciate it if i could get some answers. I am wondering if i am pregnat or is this a sign of some sort of syphtom. Please. I need answers quickly.
