Someone help??

So I haven’t had my period in 2 months (this will be the third) and I have been experiencing some pregnancy symptoms. But just YESTERDAY my vagina was peeling and I had a fishy Oder and all the symptoms of BV and today it’s all gone. No itching, no burning, no peeling, no odor at ALL. Does anyone know what happened ? (I also started drinking more water so was it ever BV in the first place?)
