I was the same as you at your stage. I was feeling left out when everyone one in my BB group was feeling movement and I wasn't yet. I thought I did for a while there but now that I know what the movements actually feel like I can honestly say I was probably feeling muscle spasms and not baby moving. I think I felt bump move at around 18 weeks just before the 19 week scan. I am feeling bump move every day now, right now in fact.
