Early pregnancy symptoms?

I have never had a pregnancy scare before, but now I’m starting to wonder!

I’ve been having that gooey discharge for a few days, and thought I’m just at that point in my cycle — but today it has a pink tint to it. I’m somewhere in the middle of my cycle, so could that have something to do with implantation bleeding? My period isn’t due for a couple more weeks.

Also, my appetite has been totally different for the past several days, and a lot of food I normally love smells or tastes HORRIBLE to me now. My sense of smell has especially been extra strong for a week or two I think. I haven’t really kept up with how many days I’ve had these “symptoms” because I didn’t consider them to be symptoms of anything until I saw the pink discharge today.

I did just have an intense workout yesterday, and I’ve heard that can cause spotting, but that’s never happened to me before. Just want opinions from people who might know more about early pregnancy symptoms than I do!
