6 days late

So currently I am 6 days late. I got off birth control about 3 months ago and had a cycle of 28-32 days. I am cramping but not like my period is coming. All my tests are negative. I have had a few faint positives but only I can see them so I think I have line eyes lol. Is there any way I could be pregnant but it’s just too early? I am so tired of buying test after test only for it to be negative.
