Hello, Your symptoms are not particular only to pregnancy. They can also be experienced with hormonal disturbances. The fact that you had a successful tubal ligation goes against the possibility of pregnancy. Yet, in the current scenario, you need to have a proper clinical assessment, get a trans-vaginal sonogram and if you have a missed period, an estimation of the serum beta-hCG titres also. The hip pain may be unrelated also. Hope you find this information helpful. Wish you good health.
