Confused Please Help Asap.

i am 20 years old i live with my boyfriends family, so before i get a pregnancy test i want to know if the sings I am having sounds even remotely like a pregnancy.

for the past 2 weeks I have had pain, well not really pain more like discomfort like the muscles are tightening and wont relax in my belly region

i go to the bathroom a little more, but not by much.

my boyfriend cooked those freezer chicken sticks that are greasy that i usually LOVE but this time it made me naucious, if this was morning sickness it was the only time i experienced it.

2 weeks before all these questionable symptoms arose, one breast hurt, then the next day the other hurt.

also for the past week and a half to 2weeks i have been having weird eating habits first of all ill eat i nice dinner (main, veggitable, and something else) ill get full and about 20minutes-1hour later ill be hungry again, and on top of that ill wake up at like 2 or 3 in the morning hungry and i wont be able to go back to sleep till i have a small snack

i am also confused because I am on deprovira (injection birth control) and i always spotted with it but all of a sudden, again in the past 2weeks the bleeding changed in color VERY little and a little heavier.

if there is anyone who has had and/or heard of a case like this please let me know,thank you very much
confused and waiting
