Should I take a pregnancy test?

I am currently 8 days late for my period my boobs have been killing me and are big and my uterus is rock solid. These are signs of my period but I have had them I wanna say two weeks possibly week and a half but about three weeks ago I had spotting when I ovulated was medium lasted two days after the initial night it started right after sex. I have pcos so it just happens randomly. I took two tests at three days late and it was both negative should I retest or just assume it all pcos related and I’m not pregnant due to the negative test. (Sorry for long post!) I scared to get my hopes up again I balled the last tests lol
