Can some help me out?

Hi guys! I have a question. A little background I have an 18 month old. I'm very unsure if I want another, mostly not but... I don't know. And I have a very weird cycle. I only had one period in over two years since I got pregnant with my son.

Fast forward to last Tuesday night hubby and I went away on an overnight trip alone, we usually use condoms but didn't and it had been a while -it was awesome 😊 -but later on I just got this strong feeling that I was prego and just had twinges and just stuff i felt the first time around.

So fast forward to today. I took a test yesterday and it was negative. But I think it's too early to test. Tweaker said she saw something but unclear. So for accuracy, when should I test again based off of Tuesday's date?
