Right after my last period I had unprotected sex, 2 weeks later I was experiencing cramping, sore breasts, mood swings, and nausea but it was too early for me to be experiencing any pms symptoms although they resembled most of them (I never get them that early). My period isn’t supposed to come for another 4 days and I had no sign of pms symptoms but now I just got what I think is my period, it isn’t light spotting but it isn’t heavy either. What should I think? I’m still considering taking a test
