Early pregnancy questions

Hi ladies,

This is my first time ttc and my first time following a app tracker. I use the Flo app to do this

My “big” ovulation day was the 23rd. Around the 27TH I started experience bloat, mild cramps, fatigue and light spotting.

What exactly does this mean?

My period isn’t supposed to start until February 8th.

Could this still be premenstrual symptoms??

I’m pretty new to all of this
