Missed period

[LElizabeth]

I am currently on my third cycle ttc and my period was due today and it hasn’t arrived. My period usually comes on the day every month as per the Clue Conceive app
The pregnancy test I did yesterday was negative, do I still have a chance of being pregnant?
I have been getting light cramps nothing like my usual PMS cramps and I’ve been nauseous pretty much non stop for a week + sore breasts.
I am just looking for some reassurance really. Should tests show up positive by now and what are the chances I could be pregnant even though I’ve had a recent negative test?

I’m so anxious so any reassurance or advice would be great please

There's always a chance until af shows. It's possible you ovulated later than usual and that's why your period hasn't turned up yet. Best thing to do is to wait a few days and test again
Baby dust to you ✨

Any advise would be really appreciated!
As background I was in the pull for the best part of 8 years, coming off completely mid March as we are TTC! I had my usual withdrawal bleed after stopping the pill and had my first natural period approximately 6 days late in my cycle, which I completely expected as I know it takes a little time for your body to adjust post pill!
I’m now 15 days late for my second natural period - I took a pregnancy test when I was approximately 7 days late and got a negative result :(! Test was taken late at night after downing a couple of bottles of water in the heat not sure if that affects anything, but wanted to see if you guys experienced something similar or have any advice? I’m a bit concerned and not sure whether it’s too early to go to the doctors!
