first pregnancy symptoms?

Hi ladies! I've been trying to get pregnant and as of now I should be around 3 weeks if I am pregnant. Last week I've been feeling super nauseous on and off all day everyday and I've been like super wet (sorry TMI) but it's not like milky color just clear. And my boobs have been super sore on and off too. So like idk if it's PMS or pregnancy symptoms. What were your weird or first pregnancy symptoms?
