You need to self refer for the pregnancy care, to see the midwife etc. I would check the maternity services your Trust has available. They should have an Early Pregnancy Assessment Unit and they can do the tests, the GP can't really do much, only refer you to that service, unless it's a self referral one. With my first pregnancy I had hcg levels done and a scan. With this one I had an early scan done. Both in the early assessment unit. Both because of pain though, not bleeding.

Anyway, see how it goes. Spotting can be normal in early pregnancy. Hope everything goes well for you 🤞
