When should I try testing again?

I was suppose to get my period on Monday. I took a test at noon on Tuesday & Im pretty sure it was negative (i should’ve tried first morning pee, i know) When do you think I should test again? It’s now Thursday and still no sign of period.

I woke up with a bad migraine in the middle of the night Monday night so I thought for sure I’d get my period on Tuesday. Had slight headache on Tuesday but nothing. No spotting or period at all. I don’t feel swollen or bloated. My nipples are sore but not my actual boobs. My cervix is still very high. I can just barely touch it. It felt a little hard a few days ago but it’s still high and getting more squishy. I have no idea. Trying my best not to stress and really don’t want to get my hopes up.

Just going to expect the worst and hope for the best lol
