so about 2 days before i moved to europe i had unprotected sex, but i am on the pill. when i got here my diet completely changed, the family i live with barely eats meat, and drinks soy milk and eats mainly fruits and vegetables etc. right away my bowel movements changed and what not...

i had my period 2 weeks ago..it was slightly lighter but i didnt think much of it at the time. now im noticing that i have really bad bloating, indigestion, sometimes lower back pain too....it could be stress from be thinking im pregnant for some reason. im not sure if anyone could help me at all...i think i have to wait a few more days to take a pregnancy test before my next period anyways. i really dont think im pregnant. but my bloating is horrible and i have NO idea what is causing this to happen. i also urinate quite frequently but maybe that is because i drink alot of water..

is this from the change in diet and surroundings? or is there a chance im pregnant?

any help would be appreciated!!!
