Early symptoms???


So I got my last period December 2-6 & for about a day I have had this weird taste in my mouth where nothing has the same taste as it usually does. I can be so hungry but Nothing sounds appetizing to me & I have had diarrhea since yesterday. Every time i eat anything it goes right through me. Every morning for a few days i wake up extremely tired as if i I feel like I didn’t even get a good night of sleep. When i had sex earlier today i went to the bathroom and there was pink tinge on the toilet paper. I definitely feel like it’s too early to have any pregnancy symptoms because I’m not even sure if I ovulated yet....has anybody else experienced something like this?
