I have. It hasn't woken me up. If it's severe i'd ask your doctor. But light cramping i've been told over and over it's just the uterus stretching. I have also been told though if you cramp like that with bleeding it could be bad, but sometimes is normal too...So ive just been watching to see blood real closely but don't stress about it. I know it doesn't feel good for the baby haha I completely understand I about freaked out when it started happening with me, but so far everyone i've talked to said its normal.
