Vanessa - big hugs my love. This is tough and only time is going to give us answers here I am afraid...

To be honest pregnancy signs are a very very poor indicator of pregnancy viability. I have hardly any and have 5 live babies. A heartbeat is a far better indicator of pregnancy health. Did your baby measure correctly for dates (give or take some)? You said the heartbeat was strong. Let that give you lots of hope....

Bleeding in pregnancy happens commonly - I have had it and that pregnancy gave me my DS8. I had lots - heavy, clots for weeks. I remember I had a clot that almost fit in my hand. I just thought it was all over. But lke you there was a lovely little heartbeating. My hope is that this bleeding stops and your pregnancy continues. It doesn't sound like you have pain? You have a heartbeat. Just surround yourself with positivity. Dream that baby to life. Love him/her - if he does go you will have loved her - if he stays she will know how strong that love is.

Keep us posted...
