5wks and cramping

Chelsea • My sweet hubby and I have been together since 2009. Our sweet Madilyn Ann born 11/5/16! We`re finally complete!
Hi ladies!
I'm 5weeks and 2days today. This is my first pregnancy. I've been cramping since 3-4 days before AF was expected and I'm still cramping daily. It's not constant.. It comes and goes throughout the day. Sometime they are very mild and other times they are very sharp. Sometimes they feel like AF cramps.
Is this normal? Is anyone else experiencing this? And when did the cramping stop for you? 
Thanks! 😊
