Hallow Dear,
If you have not missed your periods, there is very remote possibility that you are pregnant. Moreover your
pregnancy tests are repeatedly negative.
The foetal movements are felt by the mother after 18 weeks of pregnancy. By this time, the grown up
uterus is felt easily by the woman from the abdomen. If you are not feeling the uterus, the movements you are feeling cannot be that of the foetus.
May be you are having some gastro-intestinal digestive or gaseous problem. Hypermotility of the intestines is many a times perceived by woman appreciably as some movements. It can be due to
indigestion also. If so, have some enzyme preparations.
Get your stools examined from the pathological laboratory to rule out worms and/or
amoebiasis. If so, anti-amoebic and/or anti-helminthic treatment will give you relief. Also you can take some carminative preparation like
Gasex.
Please report to the physician to have a proper diagnosis and treatment.
I hope you have satisfactory explanation.
