Am I pregnant?

Okay so on October 19th me and my fiancé had sex and he didn’t pull out all the way he ejaculated inside a bit and the rest he managed to pull out and finish his business on the floor.

Mind i was 22% fertile.

On October 20th we decided to have sex again! 8% fertile And he fully ejaculated inside of me and i was in doggy style position when he was done i stayed in doggy position for about 2 mins or so.

I went to clean up cause he wanted to do second round but then i just decided to not continue cause i was really sore down there.

Next day i woke up with a nasty taste in my throat and a bit nauseous.

We’re on October 22nd and I still have the nasty metallic taste in my mouth.
