- An enlarging cyst may cause dull pain or a feeling of fullness or heaviness in the lower abdomen or back.
Pregnancy, ectopic pregnancy and endometriosis
Sometimes women in the very early stages of pregnancy experienced slight cramping, similar to mild menstrual cramps, right around the time that the fertilized egg implants in the uterus. This is termed “implantation pain” and happens right around the time of the expected period.
