Hi Joe-Anna, are you in the UK? I ask because you wrote spend £10. If you are then, from my experience you could have problems getting a MH referral (pregnant or not). It may be that your Uni services will be better able to get you a referral.
For a termination you'll need the opinion of 2 docs, but the clinic you choose should arrange that. Your MH is a valid reason for wanting a termination, your GP should have spoken to you about that.
I'd advise getting a termination sooner rather than later if that is what you want, it will be a simpler process and less traumatic.
Try having a look at Brook Home to see if they can help you get a termination in your home town.
PM me if you think I can help.
