Strange.

So I’m never late on my period. Every month AF shows exactly the morning of the 18th. Like she’s on a timer.. a week before my period my boobs felt really heavy and sore. Which seemed earlier than normal. About three days ago I got some mild cramping. I thought oh for sure AF is coming. Well here we are.. the 19th. Still no sign of AF. I am nauseous on and off last two days, feel like I’m going to the bathroom more frequently. But other than that everything seems like AF is going to start. I guess I’ll test in a couple of days but would I be having light cramping if I was pregnant?
