what was the earliest pregnancy symptom you felt?

my boyfriend and I are trying to conceive, and by now I should be 3 weeks pregnant and I haven't really felt any symptoms other than a little bit of nausea. we tried having sex during my fertile days and he came 3 times, and we also had sex the day after my period, and the day after that he came twice. sooo, in total he's came 6 times inside of me (sorry if this is gross 😅) I just really want the baby!
