super intense cramps

Kayla • 25 💕
I got my period 3/4/17. My usual cramping only last the first day when I start but the last two days iv been experiencing super deep painful cramps.. cramps iv never felt before... it literally feels like a knife is being jabbed into my uterus... iv never felt this... it's making me feel sick... it comes and goes in spurts but this is very abnormal... has anyone experienced this? Should I be worried??
