Should I wait or take a test?

Mi

This past week has been confusing for me. I was suppose to get my period yesterday but so far there’s nothing. Everything I eat or drink makes me nauseous accompanied by stomach pains to the point I feel like I’m gonna throw up and I’ve been feeling like this for the past week. Three days ago on Tuesday I noticed when I wiped the toilet paper was lightly stained light brown and light pink. Then the next day on Wednesday the toilet paper was light pink. It wasn’t heavy or anything it was very faint. Around the time I was ovulating I was having sex unprotected and my partner didn’t pull out. Should I wait and see if my period comes or should I take a test?

Update 8/28/2024: so I’m currently 3 days late as of today. I took a pregnancy test today and it came out negative. I don’t know if it was too soon to test or if that’s actually my results but still no signs of my period.
