Hi Everyone

I have a question, i am now only in my 8th week but i have been getting sort of flutters in my belly (kinda like a muscle twitch) its been happening for about 5 days or so now, i am wondering if this is normal or what is going on, talking to mum and mother inlaw they say you should not feel anything till about 18 weeks. not due for my first scan for another 2 weeks. I just thought i would ask see if anyone else has experienced this before.
