Cramps (Not PMS/AF)

Early pregnancy symptom

Cramps in early pregnancy are not only common but very normal. Some women feel cramping as early as implantation when the embryo attaches itself to the uterus (6-12 days after ovulation). Others may start cramping after their first positive pregnancy test as their uterus starts preparing to carry a baby for nine months. The uterus grows quickly in early pregnancy and cramping is expected.

Some women report the cramps they experience in very early pregnancy are quite different from their usual PMS or menstrual cramps. Others say they are similar to the cramps they experience just prior to or during menstruation (and some may dismiss them as their impending period), or feel like mild pressure, or quick sharp pains.

If you are experiencing any pain that does not seem "normal" or that is very painful, you should consult your doctor, especially if they are accompanied by bleeding.

Includes: Cramps that feel different than PMS or period cramps.
