Pregnant?

Been ttc for about a year now for #2, 4 days till af with a negative test today but have been having a lot of symptoms I usually don’t have before period. I’ve been extremely bloated lately, loss of appetite(had that my last pregnancy), heartburn(which I NEVER have and didn’t anything unusual or spicy that whole day or surrounding days) I’ve been somewhat sweaty lately even though it’s cool inside and I went to a doctor twice in 2 weeks and my pulse has been high both times, and today when they checked it they had me sit for 15 minutes and took it again and it elevated from me just sitting there but bp was completely normal, I’ve heard that could be a symptom but wasn’t sure. Has anyone else had symptoms before getting a bfp?
