Was told I couldn’t have kids

Angela

10 years ago I had a miscarriage and was told I couldn’t have kids due to fibroids on my uterus and that if I ever did get pregnant again I wouldn’t carry full term. I’m finally pregnant again but now worried and trying not to be. I have been wiping brown (old blood) every day since my period was supposed to start and at one point actual blood. I have doctors appointment Monday but should I be concerned? I really want to have a kid. According to my tracker I would be a little over 6 weeks
