AF vs pregnancy

Did anyone ever experience their normal pre-af symptoms but still went on to get a BFP?

All of my normal pre-af symptoms started to come as of yesterday and I’m 5 days from AF. I’m worried I’m out already with these symptoms because this is about the time they normally show up. I know everyone says we aren’t out until AF shows but I’m just wondering if anyone else thought they were out because they had their normal PMS symptoms but ended up being pregnant.
