I had a similar experience to Karin when I went to my GP the first time after finding out I was pregnant -- I felt a bit blown off, even though I was having some problems. (I told her I was having severe pain on one side, and she just said "Pain is normal during pregnancy" -- that's it, no asking about my medical or gyno history, or examining me or anything.) It seemed the only point of going to the GP was so that they could fill out forms and refer me to the hospital and midwives, but do you need a doctor to do that? It was confusing.
I was supposed to see the midwives at 12 weeks but since they notified me about my appointment by mail and we were having all those unofficial postal actions in London, I never got the letter and missed the appointment. (Side rant: why do they notify people of important medical appointments by mail?
especially when everyone knows the post isn't working properly? sigh...) So I didn't see the midwives until 15 weeks.
As a first-time mom I had loads of questions -- not just about pregnancy, which obviously you can buy books for, but about how things work here in the UK, which is a bit more difficult to find out about because every locality and practice does things differently. I do think the laidback approach is better overall, but I think if it's the first time it is a bit stressful not being able to see anybody for the first couple months, which after all is when you have the most questions and probably worry the most about symptoms and complications.
For the OP, I would echo the earlier suggestion about the Early Pregnancy Unit at your local hospital, and suggest finding out if you can self-refer if you are having problems. At my hospital they prefer you to have a GP referral but it is possible to refer yourself to the emergency gynecology unit (which is open 24 hours) including for early pregnancy problems like pain and bleeding. I eventually went there for a scan and they were great.
Also I highly recommend getting the What to Expect book, it's great at talking about early pregnancy symptoms and when you should call the doctor, it's SO reassuring!
