I have been unable to describe this to Google it but here goes:
Weird feeling comes over me
Feels physical but vague
Not pleasant but not painful
Lasts a couple of seconds but may return quite soon
It's a bit like a rush/ tingle but doesn't actually tingle
Gives me the feeling that there's something I should be doing but I can't tell what, it's as if it's an urge towards something
Am 21 weeks pg but have been having it for a few weeks now, usually in the evening but not always
Anyone else? Any ideas?
