and yeah, i just read your next comment - i find the same thing, if i get up suddenely, feel the pain abit more.
I thought about a doppleer as well, till my SIL said to me how will you feel is bubs has moved to a spot where you cant hear the heart beat. They say that the dopplers pick up heart beat from 10wks, but others on this forum have been told by their midwifes/obs that they cant pick the heart beat till older, or even at 1 checkup they can hear heart beat, next they cant.
IMO - we got enough to worry about with aches and pains and that will only ad.
