I was having sharp pain in my stomach the other night and I called my dr. (Never had it with my first). The very first thing they asked me was if I had an ultra sound yet. I said yes, but if you haven't they might want you to go in. Since I had an ultra sound and everything looked good, they told me to take a hot (but not too hot) shower and see if that helps and it did, so maybe try that and they also told me that if it ever lasts a really long time (like an hour+) then to go in. Just to let you know though, my pain had me in tears and it woke me up from sleeping (although who knows how I moved in my sleep). I am 10w3d.
