HELP!!!! LATE PERIOD & PREGNANCY SYMPTOMS

So on the 5th June I came on my period, I then came off on the 12th (I usually stay on for a week so that’s normal). I then went on holiday and took some pills a little later than I should’ve done! I came back and not to be graphic, there were 2/3 occasions per day for a week once I came back that I could’ve conceived. On the weekend of the 28th I had some light bleeding but not a lot at all!

I’m now 3 days late:/ I usually operate like clock work! Had 4 tests and 1 was VERY faint but faded (weird!) and the other 3 were negative? I just want to know if I am or not lol! It’s killing me😂

Any help guys????👶🏻💛💪🏼
