Can a man have symptoms before bfp

Cara

Ok so I’m not due for my period for4-6 more days with a 26-28 day cycle I ovulated on the 14th day with spotting I had sex the day before the day of and the day after a week later my bf throws up and I have a bit of nausea and then period cramps the day of and the day after he threw up can this be a early pregnancy sign for me considering he never throws up I was 8dpo now I’m 9dpo with more cramps
