I'm just over 6 weeks pregnant today and since yesterday I've been lightly spotting on and off. Its only on the toilet paper after I wipe and in the last 24 hours has happened about 3 times. It's light pink. I've also been cramping on and off for the last 3 weeks (period like cramps). Is this normal? This is my second pregnancy and none of this happened with the first. My OB won't see me til I'm 8 weeks.
