Hi guys, I'm sorry if there is already a thread for this but having searched the Internet, I cant see anything relating to my exact question. So basically I am pregnant for the first time and I'm currently 17 weeks & 3 days. Today I have felt what I can only describe as muscle spasms in my lower abdomen. It lasted for a few minutes, maybe 20-30 seconds apart at a time, sometimes quicker. I know this can be the baby moving, however I also physically saw my stomach move at the same time. Surely its too early to see this? I am of slim build, normally size 10 clothing and I have a posterior placenta. What do you guys think?
