TTC. ovulated and had sex 5 days ago.

Hey all! So me and my partner have been TTC for 5 years 😫
We had sex 5 days ago on my peak fertility day. Three days later I started to get thrush like symptoms. My partner doesn't have any symptoms at all. 
Could this be an (extremely) early pregnancy sign?
I'm bloated more than normal too.
I keep telling myself to not overthink as previous months have always told me: I will not be pregnant.
Just curious as to wether anyone else has experienced this. 
Ps; I have only ever had thrush when I've been on antibiotics before. Never had it out of the blue.
