Flutters? Spasms?

Amanda
Hi all! I'm 9 weeks and 4 days now. Today I started having these spasms in my lower abdomen, similar to when your eye twitches. They're way down near almost my bikini line.
I know it's too early to be the baby. Does anyone else have these? Is it just the uterus stretching? 
Also, has anyone woken up and had no morning sickness some days and been very sick others? Thanks!
