So ladies I'm almost 21 weeks pregnant with my first baby. Lately I've been feeling worry and fear of loosing my baby after I fell in soo much love with him. Don't get me wrong thank God all went very well in my 20 week scan and they told me the baby is very happy and healthy but my dumb ass keeps coming upon these horror stories of moms losing their babies after 20 week mark and some even around due date I also heard the chances of that happening are rare but can someone just knock some sense into me I think that's what I need lol. Thanks ladies
