Pregnancy symptoms

How soon did everyone get pregnancy symptoms? I had sex with my so on Sunday morning and we both have a really strong feeling that I may be pregnant ... kind of like something is just telling us I am . My mother and his both have asked me if I am and I know it is WAY too soon to tell. Sunday was a day before my “ovulation day”. Just asking for other people’s experiences and opinions or advice. Has anyone ever had that “gut feeling” and was actually pregnant ?

**Update**

It’s been 6 days since possible conception , I have been having some cramping and been pretty nauseous but haven’t really thrown up! I have had people ask me out of the blue if I was pregnant which is weird
