2dpo...sense of smell

We aren’t ttc actively but we aren’t trying to not get pregnant...according to the app in 2dpo.

My fiancé has a really heightened sense of smell and my nose is more sensitive than his! I can smell the dinner I cooked and it makes me feel sick!

Had headaches the last week (not like me)....and plenty of vaginal fluid!

Any ideas?

I know that you don’t get pregnancy symptoms at 2dpo, but these are unusual ovulation symptoms for me... what causes that change?
