When to see the gynae

Hi, first time pregnancy. Didn't had my period for 2 weeks and decided to just test yesterday with clear blue digital and it said I am pregnant and conceived 2 - 3 weeks ago. Not very sure how to count how many weeks I am into pregnancy and also due to my irregular period, I didn't think that I was pregnant. Last period was 6 Nov. Please advice if I should see gynae soon and how long am into pregnancy. Thank you 🙏#pregnancy #advicepls #1stimemom
