Period or implantation? What’s going on??

Hey guys so I have a situation that I could really use help with. I had a really weird cycle I just went through. My fiance and I took a brake from trying so I’m not sure when ovulation really was but I think it was later then normal. So about a week ago I went through some cramping a week before my period was supposed to start. Which is really strange for me because I normally have cramping the day before and the day of my period. I started getting almost an instinct feeling that I’m pregnant so I took a test the day I was supposed to start. It was negative.

About 3 hrs later I started bleeding with light cramping and regular blood so I had assumed I just started my period since it happened on time. Then it tapered off quite a bit throughout the day getting lighter and lighter. That evening and the next day it was just pink and brown. I typically have my period for three days but it was really just two days with some brown spotting on the day. Nothing happened on the fourth day.

It is really unusual and I’ve never had that happen to me before so I took another test today and it was negative. I feel so lost and confused. In my heart I feel like I am but I don’t want to be unrealistic. Other symptoms I’ve had are nausea, headaches, boob soreness, moodiness, and loss of appetite. So have two questions for everyone on this journey ❤️

One: Has anyone experienced something similar to this and ended up being pregnant?

Two: How long after this weird bleeding should I take a test again??
