When the baby drops, you feel the need to pass urine frequently and feel lesser fetal movements. Braxton-Hicks
contractions are transient and are not painful unless they are very strong. If you get relief from the cramp by lying down, then it could well be one. If you do not feel any relief from the cramp and if it comes repeatedly on, you should consult your obstetrician immediately as this could well be pre-labor
. This could sometimes be precipitated by constipated bowel and excessive stress
. Watch out for spotting or watery discharge. Please take further suggestions from your doctor. Take care.
