Cramps (Like 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 similar to the cramps the experience just prior to or during menstruation (and some may dismiss them as their impending period). Others say they are quite different from their usual PMS or menstrual cramps, 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 just like PMS or cramps you would feel during your period.
