Infection or pregnant?🤷🏼‍♀️

So I’m feeling so nauseaus, constantly needing a wee, my lips have become so dry and Ive got a very tiny amount of white/creamy discharge when usually I have a fair bit... I’m 4 DPO so dont know if it is a Water infection (Ive been drinking cranberry juice for past 3 days and hasn’t really helped) or the possability of being pregnant but doubting this because of how soon after ovulation?! I’ve also been bloated slightly more often than not and have done a test which come back negative but as I said, it would be very early! Advice pleasseee (Dr’s appointments are very few and far between right now because of the virus😩
