When to test after doing the deed

Rose

I was going to wait until my first period after coming off the mini pill but my partner got a bit keen and finished in me twice on the 14th. I was on the combined pill for 8 years on and off and always had a 28 days cycle when I came off. I have no clue when I should test as I've read online 2 weeks then 3 weeks in other places. If my cycle is a normal 28 days I'm due on in 6 days.

I reallly appreciate some advice.

Also is 6 days later too early for symptoms? My nippples have felt slightly sore and sensitive over the past few days but today I woke up feeling a bit bunged up in the nose

and feeling sick here and there.

Thanks
