I am 23 years old and had a miscarriage last year at 8 weeks. Although, since the beginning of that pregnancy things were looking strange (no baby seen in ultrasounds was the main thing) well now I'm going on 16 weeks on Saturday. Tomorrow I have my 3rd appointment, and so far everything has been going well (baby seen in ultrasound, good heart beat, all the blood results and pap smear are good) but I guess behind my head I still worry. Hope some answers will make me calm down, thanks.
