hi there

has anyone experienced sudden sharp pains in the lower abdominal region (i guess where the uterus is!) when they stand up quickly or move/roll quickly? I am 7 weeks pregnant with my 2nd bubs and I have noticed in the last few weeks, every now and then when i stand up or move quickly, i get a sudden sharp pain in my lower belly - it's gone as soon as it arrives, but it makes me double over. i'm a bit scared, although i think i remember this happening with my 1st pregnancy but that was a while ago.... is it normal? or should i be worried? the pain seems to be in different spots although lately its been the same side/spot. help!
