Sorry to hear you are so scared hun - pregnancy is such a worring time. All i can do is share my story - i had spotting & bleeding right up until 17 weeks, never found a reason for it. I am now 38 weeks and thankfully all seems to be well with babs. I was always asked when i went in to hosp with the bleeds if i had had sex, never had before any of them but apparently it is very common.
I never bothered to ring the hospital for any of them, just turned up at the early pregnancy unit and they have to scan and examine you then. Would you consider doing that? I know with me the only reassurance was seeing the baby move and a heart beat on screen.
I am sure everything is OK with you hun - bleeding during pregnancy is so common, if a scan would help reassure you then i would head for the hospital. Once the bleeding is a once off and you have no cramps or pains i was always told it was very unlikley to be anything bad.
Hugs xx
