I thought I felt something yesterday but been told I'm too early to feel anything. Felt like a gentle finger stroke from the inside. My friend has had a bubby and is preg with #2, for her first she didnt feel anything till 20wks, for this one she started gettin kung-fu bashed from about 12 weeks onwards. I'm not sure if 7 weeks is too early, if your muscles are still a bit weaker and stretched from the previous bubs then hey who are we to say its not possible
