Pregnancy scare?

I had my period may 25-31st I had sex on the 7th 8th and the 9th they were all my ovulation days I began spotting very lightly over a week ago now it was pink and clear mucus looking and it lasted for 24 hours that same day i took a pregnancy test I’ve been drained like more tired than usual, I get dizzy spells a lot and diarrhea everyday. Did I take a pregnancy to early and should I take another one I still have yet to have a period well an actual real period this has never happened before.
