Omg!!!
I didnt have one with DS until i was in labour but this time with DD i did. I had one on the tuesday morning - brown blood though, then little bits here and there through the day. Went into pre-labour wednesday morning, full labour wed night and dd was born 2am thurs morning. It wasnt quite 48 hours between my show and when she was born. Sorry i cant answer your bleeding q as mine only came out when i wiped and it wasnt really blood, it was bloody mucous.
Sending lots of labour vibes to you xxxxx
