The chances of you getting pregnant after a bilateral tubal ligation
is less than 1.6%. But just to be clear, your symptoms beside the intermittent pain/contractions do not look like that of pregnancy
. You gain weight and not loose it when you are pregnant. You might be having intestinal colic or an intra-abdominal tumor
or another illness that needs to be looked closely by your doctor/gynobs by running some test including an abdominal ultrasound
. If you are suspecting pregnancy, I will suggest you start by doing a pregnancy test by using urine test strip
or dosage of hCG levels in blood. After which an abdominal and pelvic ultrasound needs to be done.
Hope this helps
