Hi, My Name Is Jessica. I Just Wanted To Ask

hi, my name is jessica. I just wanted to ask a few questions that im quite unsure about. well just like 4 hours ago my friend had sent me a home pregnacy test using bleach, and urine, the test indicates that if it bubbles up, and stays that way, then your pregnant, and if it doesnt bubble, then your not. well mine bubbled and stayed, so i tried my little sisters pee, and hers didnt bubble or foam. So of course i freaked, and looked up another at home test witch was sugar and urine. . it said if its a positive result mixing sugar and pee, then it will clump, but if your not it will desolve. Mine clumped. i even stirred it and it didnt dissolve. Im freaking out. I havent had sex in 3 months, had my periods, but having more lower abdominal pain than usual, White thin discharge coming from the vaginal area, and my boobs hurt. I went to the doctor in october, and they said it was a negative pee test, no blood test was done, and i took one myself at home around september and negative. Im still having my periods monthy, so im a little confused. What should i do as of now?
