As long as you see a doctor in the first 12 weeks you're fine They usually will give you your referral to a prenatal clinic/ob/hospital, depending on your choices. They will also order blood work & possibly even a scan. Maybe some extra tests.
Just so you know, if its been about 6 weeks since you had AF (monthly friend) then you are about 6 weeks along. They date from the first day of your last period.
The sledding should be ok, since there are alot of people at this stage who don't even know they are pregnant yet

Congrats & welcome to BB
