Help am i pregnant.............?

I got my period three weeks ago it was a bit shorter than usual. i then had diarrohea this stopped then i couldn't go to d toilet for a week.i got it again a few days later (after my period) but it was a brownie colour. I dunno if this is cause i was late going to get my from doc. But any way was taking d pill and it started again once again a brownie colour. During this time i have had lots of pains (not my ). i had lots of brownie discharge in between. My friend told me dat my eyes were glossy d other day and she said dat this is d first signs of pregnancy. I have also been drinking a lot more lately and also weeing a lot more (prob cause i drinkin more). I stilol keep gettin pains. I haven't taken a test as i think it is to early.
