Agh help!

Okay so I had what was a seemingly normal period on Oct 6th. Lasted as long, pretty heavy for a couple of days. Although not painful really.
I've been feeling quite sick for a few days or more but been putting it down to being a bit stressed. Also lost my appetite.
This arvo, I found an Internet cheap strip from when I was actively ttc so did it to set my mind at rest as been feeling sick all day.
After the 10 mins there is a faint line there. I'm not sure how reliable these are but assumed that if I did it now and I was pregnant that it would be much darker.
So then I found a tesco digital thingy (yes definitely last test hidden) and squeezed a very diluted pee out. That said not pregnant.
I'm probably in the clear now right?
I'm in 2 minds whether to get a supermarket test just to be sure and use in the morning, but figure if the digital one says no and last period was so long ago, I couldn't be pregnant.?
Could I have some wise words please? I'm not actually stupid but a bit freaked out by the first test strip.

Right I think it's an evaporation line. This is the best photo I could get but it's a bit more pink really. I may have just freaked myself out for nothing.

If your last period started on 6th October as you say, if you have a standard length cycle of 28 days, you probably won't have ovulated yet. So probably unlikely that your are pregnant. Not impossible, but unlikely.
However, digital tests tend to be a little less sensitive than some others on the market. If you need to try again in a few days, try a standard supermarket or chemist own brand, they usually pick up low quantity of preg hormone.
I can't really see the cheapo result pic.

What I mean is that I'm not sure if the last bleed was indeed a period. If I'm going by the period before that one, I would still only be just under 5 weeks iyswim.
And no I have 25 day cycles usually
