TTC aft miscarriage.

Hi. Ive had a mc 3 months ago but recently we started ttc for this cycle and ive got faint positives for the past days. My period due date is tmr. Could i possibly be pregnant? Using watsons house brand. Dont know how accurate it is. If i am preg, is it possible to see a gynae now or should i wait a week after my period due date? Not sure if i can see the gynae so soon? The last time i visited when i was a week late. Im so afraid i will end up mc again... so just want to know if gynae can prescribe some meds when u just turn preg to ensure pregnancy runs smoothly.. ? First time ttc after miscarriage so im not really sure what should i do now. I am also changing my gynae as i dont really like my previous one.. Pls advice on what i should do next.. thank u so much.
