Im sixteen, my last period was june 1st, i didnt have my period in jully or august. I took 1blood and 3urine tests all came back negative, i was/am so confused i had/have pretty much all the pregnancy symptoms, headaches, stuffy nose, sore breasts, rise in temp, mood swings, bloating, and when i feel just bellow my belly button it feels hard. Everyone said my levels of hcg could just not be high enough to detect yet. But sunday night (9-1-13) i started spotting light brown-reddish. Monday morning (9-2-13) i started bleeding with small blood clots, today (9-3-13) im still bleeding but its a bit heavier and still with small blood clots.. Could i of been pregnant and am having a miscarriage? Or could i still be pregnant and going through somethng odd?! Some please help. Advise or stories would be greatly appriciated!!
