Spotting TMI

Hi lovely’s so I started having brown spotting last night, and this morning it went from barely to absolutely nothing. I have cramps, mild, and my period is suppose to come on this week! But, I’ve never spotted and it stop before my period??????????

What could it mean?

I don’t know I feel like I should know considering I have a six month old but I didn’t pay attention to signs the first time and we are trying again for baby #2 and we’re confused 😭
