kinda anxious

🎀S
I'm pregnant and its three days before my period is supposed to come and I've been cramping all week my only other symptom is sore boobs. The cramping is very light but I've been getting it since Monday.  I'm just worried because I know before my period is due and I'm just wondering if my baby will stick 😔😔😔😔 Anyone else cramping? I haven't bled a drop not even brown or pink
