Crazy information but help needed

This is what my period was this month. My periods usually always look like this with two months of spacing in between. The 12th through the 15th was light bleeding with no cramps. On the 14th I had sex he didn't cum but precum could maybe be possible I'm not sure. But 5 days later I got a yeast infection which wasn't because of sex. But it cleared up on its own in about three days (today). Yesterday which was 7 days from when I had sex I had this watery rustyish orange like pink and brown mixed together. And today its a peachish kinda pink color both days the bleeding was so light I can only see it when I wipe. Do you think this is implantation bleeding / pregnancy related? (I know this is a lot of weird information but I could REALLY use some advice)
