When did you book in to see doctor

Shianne • I`m 20 my partner is 22 we have been ttc for 2 years with 1 MC last year in August at 8 Weeks :( RIP Angel baby xo.
Just curious to know how soon everyone went and got blood tests etc when you found out you were pregnant ?? 
I took a test last night positive LMP was 30/4/16 which means I'd be 3 weeks 1 day 
Should I wait a few weeks or go straight away??
Note ; I've had 1 miscarriage in August last year xx
