I Had Unprotected Sex With My Fiancee On Saturday October

I had unprotected sex with my fiancee on Saturday October 24th and got my period on schedule October 27th Tuesday. It only lasted a day and then very low spotting from Wednesday to Saturday. I took 3 pregnancy tests 2 incomplete question mark results and one negative line. I've experienced fatigue, breast changes, and nausea. Should I wait and take another test or am I out of the woods?
