heya im replying to u because i had a miscarrage on my 15th birthday, wel i will tel u how mine started. i got like a little period n den little cramps at about 12 at night. then i woke up at about 2 in the morning and sat there by myself with really really bad pains, like some1 was stabbing me in the stomach but i didnt want to wake anyone up so i stayed there but then they got worse and i started crying and i woke my friend up because of this. then she woke my mum up and i couldnt even walk becuase the pain was sooooo bad, we had to ring an ambulance and i went to hospital, i lost alot of blood and had to have a blood transfusion and had to stay in hospital till 3 in the afternoon, this was on my birthday, my blood was clotty aswell, u could of had a miscarrage but if u wer preggers a test should of showed up positive by that time. go to a doctor if u havnt already and see what they say. hope this helped you love beth
