Totally confused plz help😢

Kaden 👦💙 2017. ttc #2

Hi, I am 2 days late and no sign of af and also dont fell pregnant (no sore boobs, cramps...) but i have diarrhea (tmi sorry) for 2 days now especially early morning. I normally go from constipated to loose on the day of af and just once. But i am confused as i also have lil twinges on my left ovary. Anybody experienced that and ended up pregnant?
