Four negative pregnancy tests but feel bloated

Sofia

I’m 9 days late for my period, two days ago I took two tests and it’s negative- and 5 days before that, two more negatives. But, I feel bloated and nauseous- note I don’t want to be pregnant, and I’m wondering if the nausea is just anxiety that I am pregnant or if i could still be pregnant. It’s not like I didn’t wait long enough to test right? The brand was clear blue, by the way. Any advice? Also, I did use first morning urine.
