i was pregnant at sixteen with twins, but had a miscarriage. i really wasnt aware of symptoms or very in-tune with my body at the time. the only signs i remember are that halfway through the month, i went to the bathroom and found one single spot of blood in my panties. then, i waited the entire month for my period, and it never came. so, the first week of the following month, i took a pregnancy test, and it was positive. i never had any symptoms, no sore breasts, only cramping. im still not sure if this was due to the miscarriage.
