When to go to the doctors 😱

Brittany
So I recently revcieved my BFP, I've previously had one healthy full term pregnacy now two year old I've also had two miscarriages end of last year early this year back to back. My question is when is the right time to go to the doctor seeing as AF isn't due till the 4th? And can I request extra check ups during this pregnacy to ease my mind ??? Please help me 😊😊
