Has anyone had a random unexplained bleed at around 21 weeks? I had a sudden bleed yesterday, went to loo and was bright red when wiped and then had further bright red bleeding for an hour or so followed by brown bleeding up until now. No particular pain. Went to maternity unit where they listened to baby hb and kept me in overnight to monitor bp but was discharged today as bp was normal. They haven't given Ny reason for it but I can't stop worrying now!
