6th miscarry this month

Lori • 16 yrs old and after having 5 miscarriages and not being pregnant this time iv lost hope, myb ill never have kids :(
Went to doc and she said I was miscarrying she said the reason the pregnancy test didnt pick it up that I was pregnant was because my body wouldn't have put out enough HcG because my body new it would be hm getting rid of it :'( I'm really upset and i have to go and get tests soon :( and ill probably never be able to have kids ! Just wondering if anyone else has had this ?
