I need support from those who received their BFP

Been TTC for 6 months. Had sex 5 days straight right before ovulation. Finally having some pregnancy symptoms like nausea, fatigue, slight cramping , creamy white discharge that switched to very light spotting 6 days before period, moody, and vivid dreams ( I don't normally dream) . Im hoping i finally conceived and im not prepared for another heartbreak that I didn't. my period is on the 21st is it to soon for me to try a pregnancy test? This wait every month is killing me and my spouse 😧 .
