Hi,
Welcome to ehealthforum.
The symptoms of movements could also be due to gastritis. Visit your doctor/gynecologist for further evaluation. If pregnancy is suspected (possible due to spontaneous recanalization of fallopian tubes), consider visiting your doctor/gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). If pregnancy gets ruled out, further evaluation would be done to look for the underlying cause (hormonal derangements, thyroid abnormalities, endometrial changes, anemia etc) for the altered periods that you describe. Treatment measures as indicated (based on examination findings and investigations results) would be started to help you regulate your periods.
Take care.
