I hope your scan goes well tomorrow. xx thinking of you. It's so nerve wracking isn't it!?
I went to my gp with my first m/c and got a referral for bloods and scans from her. she also reffered me to the early pregnancy service at our hossy. maybe that's worth looking into. to see if they have one. i went to them straight away for my second. they do all bloods and u/sounds generally same day. you just go see them for any concerns up to 20weeks even if you dont miscarry.

Can you go see another gp?
