Two days ago i woke up and went to the restroom and had pink spotting/discharge. Then within that whole day i had brown discharge. Nothing since then.. Could that have been implantation or what? My period isnt due for another week. I've been cramping. And I've had tender breasts. Towards my nipples they've been tingly like its hard to describe. I've been super emotional. For no apparent reason at all. Thoughts on this? Thanks 🙏
