Around that time of the month i get a heavy pressure feeling and when i have sex the same feeling happens except worse, its happening on my left side.

Pain & Period: One sided discomfort just before period and similar pain on same side with sex, makes me wonder if you might have endometriosis or perhaps a fibroid (small, benign growth) on that side of your uterus. Best to see gyn for exam and possible ultrasound. Hope this helps. Sorry you had to wait for answer. Good luck.

Menstrual symptoms: Women often experience cramping, nausea, headaches or even some food cravings in the perimenstrual period when hormones are changing in the body. Some discomfort experienced may be worse for some individuals. If you are having symptoms on intercourse, it would be best if you get yourself checked.
