HELP: 8 days late with a few weird symptoms!

So I am 8 days late and have been experiencing diarrhea for the past week, and my hands and feet have been weirdly hot the last couple of days.

We had sex last january 12 (last day of period) and 13. We did use condoms each session but there were strokes when we didn't.

I dont feel my usual period cramps, breast tenderness, and moodswings. Also no usual pre-period discharge.

Could i be pregnant? If i take the test, could it be accurate? Pls help! TIA!
