could I be pregnant .

I've had pregnancy scares before but I am not so sure this will be a scare. I got off my period last Saturday and have had un protected sex with my S/O pretty often. yesterday was my supposed ovulation day according to glow. But I've been extremely emotional and tired and not bad but kinda craving things I don't normally eat. ? I felt nauseous after both meals today but just a little . I don't know if it's to early for symptoms or what this is ? I spotted 2 days ago even though I am not supposed to start my period until next week . it was extremely light also . And my discharge has been kinda strange but not super strange. ? what could this be 🤤😭🙈
