Anyone have a false positive pregnancy test?

Ever had a false positive pregnancy test? Or even a bunch of test that were negative and you actually were pregnant.. I’m 7 days past a missed period.. and I got a bf “yes” on a first response gold digital.. I then tried 5 other brands and all negative. I’ve been nauseous, sore boots, cramps like no other, beyond pmsing emotional - Help ! So nerve wracking :(
