pregnancy

Okay , so I had my period about the time it was due. But, it only lasted two days and I'm usually a 5 day. I started having really watery discharge for the next couple of days. I started cramping at work earlier today too. I come home to wipe and I have a watery discharge with some blood on it. I wiped again and there was nothing but clear discharge. I'm not on birth control and don't use condoms. Thoughts on when to take a pregnancy test? 😬
