I'm scared can you help?

So last week I ovulated and I'm not feeling well today I feel dizzy if I haven't ate I'm nauseas I feel a bit of anxiety too . Yesterday morning I woke up and I was staining a little light pink color . My ovoulation was done 2 days ago by I have been having unprotected sex that whole week sometimes he finished inside me sometimes he wouldn't . But the thing is.. We've been trying to conceive for the last year I gave up a couple months ago I'm not sure if I should take a pregnancy test or not ? This is how it looks today
