So i'm 11w & i've lost 4lbs since the start of my pregnancy. i've also been very constipated (only go once a week, & it's been a while) so i imagine once i go i'll be even lighter. i started at 138 & now i'm down to 133.5, is this ok? i thought by now i should of gained at least a few lbs but it seems to steadily be going down.
