Cramps are normal in early pregnancy so they most likely mean absolutely nothing. The runs is also something some women can experience in early pregnancy. I've had it a few times during this pregnancy and all is well with my bubs. I think in my case I got the runs instead of getting morning sickness - it was my body's way of expelling unwanted toxins. I don't think pinkish mucas is anything to worry about but if it develops into bleeding that's a different story. Best of luck.
