Pregnancy/period?

hi! i have skipped the last 2 months of my period but the preg. test say negative. I know excerise, diet, sleep. stress, surgery and habits can all change your period. I have had majior changes in ALL of that bec I broke my leg also 2 months ago (actually i was on my period when i broke it and that was the last time i had it) . Is it possible im preg even though i have taken a ton of tests and they all say no or should i chalk it up to the changes with my leg. I can not go to the doctor im compeltly bed ridden for now
