Sorry to hear that @LaSurprise, if it's light then it probably isn't an issue, but it must be scary. At my midwife appointment, they gave me some phone numbers but said for any concerns I should call GP, A&E or Maternity Day Assessment Unit. The day assessment unit is open Saturday and Sunday, or A&E can possibly refer you, so it could be worth trying even if EPU is closed.
For blood tests, it depends on your own risk factors whether it matters or not. The information is clear though that sickle cell and thalassaemia tests must be prior to 10 weeks. They also check for urine infections, general check on iron, folic acid etc. If you have other risk factors such a diabetes, thyroid problems etc then those will be tested too. It's a useful health check given that these things can all affect the baby.
