Am i or aren't I

We DTD 3 weeks ago and I was suppose to start periods last week on the tues so on my app it says I'm now 6 days late.
The weekend before my periods I have light pink spotting on the Saturday night little more spotting on the Sunday and by monday evening it had stopped. I'm confused as if it means I'm pregnant or had a really early very short light period.
My periods are back to being regular since coming off the pill 2 years ago and i track them using a app
So far I've done 3 tests 2 didn't work at all and one came back negative but not sure if its cause it may be too early or cause it wasn't my first pee of the day as we have a pup and were up throughout the night with him and I go to bathroom then lol
I had a few nights of waking up and being itchy ive now had diarrhoea since Friday sometimes I feel queasy but not sure if its done to the fact I've not been eating great woke up this morning with a sore back plus there's times where my tummy feels full

I'm so confused right now

I would grab another test and check tomorrow morning with FMU and see. If you had light spotting that could have been implantation bleeding. If AF doesn't show up maybe contact gp.

We picked up another pack of 2 tests yesterday as the pack i had had 3 in the box 2 normal and a digital one
I had spoke to doc yesterday regarding diarrhoea over the weekend and said to her about missing Tuesday period she told me to take a test and let her know

When do you think you ovulated? If 3 weeks ago then most tests would pick up a pregnancy by now. I always see these threads from people asking “could I be pregnant even though the test says no” and realistically, unless you’re only testing a few days after you ovulated, almost every test picks up a pregnancy from 14+ days post ov. I know how it feels to be desperate for a positive (we are also TTC #2) but I know that if the test says neg, I’m not pregnant
