Am i worrying too much?.?

past couple weeks, i been throwing up, stomach pain, weak and dizzy, my feet hurt, my boobs hurt, i gained about three or four pounds in a little over a month, and i expect thats from the change in my appetite. two days ago at work, i fell the the floor crying in pain. last night when i woke at three in the morning to get a snack, i fell to the floor, weak. my sleep pattern has been messed lately too. but this morning i woke up, wet. when i looked there was blood on my sheets, and i used the washroom, and the water was pink. im not suppose to be on my period til around july 14th.. what could be wrong? anything or nothing? am i just worrying over nothing or?.. i need some help before i decide if i wanna head off to the hospital or not.
