When should I test to get a bfp

I’m pretty positive I’m pregnant with #3 but I just got off the mini pill after not even using it for a full cycle because it kept causing me to bleed non stop and be extremely hormonal.

I stopped taking the pill nov 2nd and started my period for 8 days pretty sure I Ovulated between the 13th -16th my hubby and I did the bd every other day/ every two days until the 20th. I believe I had implantation bleeding from 22-23 (tmi stretchy ewcm with streaks of blood in it). I know I’m pregnant I’ve had round ligament pain and lightning crotch and super stretchy ewcm which I personally only get when preggo I’m taking naps peeing 24/7 and just not feeling great. but with my last two pregnancies I was over a month late before I even took a test (I have irregular periods pcos probs) so how soon should I take a test to get a BFP? I took one yesterday & BFN and it totally messed with my emotions. My husband is in total denial until I get a + he thinks the mini pill caused me to have pregnancy symptoms 🤦🏽‍♀️
