Completely normal - home testing kits are as good as and possibly even better than the cheap job lots that GPs have for urine testing which are just for emergency situations to diagnose pregnancy like someone with abdo pain where it could be an ectopic pregnancy. Blood tests are for monitoring in complex situations like suspected ectopics/molars/tumours/miscarriages rather than just confirming a urine test.
Unless you're on regular medication that might cause issues in pregnancy or have other health issues no need to see a GP.
Check the NHS website pages for advice on supplements, foods to avoid & alcohol/smoking etc. before you see the Midwife.
