No signs of period!

The last 2 cycles my period has started on cycle day 28 this month I’m currently cycle day 31 and I have had no signs of my period showing at all normally I get cramps, sore boobs a day or 2 before but nothing, I’ve taken a pregnancy test and it was negative, I wasn’t tracking anything this month so I’m not even sure I’ve ovulated or if I have I don’t know when. Just want my period to hurry up and start so I can track again or to find out if I’m pregnant or not! One thing I do know is I have felt exhausted the last day or 2 maybe a pregnancy sign? Going off my last 2 cycles I am 3 days late and just getting negatives has anyone else had this and ended up being pregnant?
