I have a feeling in my vagina similar to when you're about to get a period and i'm 23 weeks pregnant, is it normal?

Depends: It depends on what kind of feeling you have during your period.There can be a fullness or heaviness because of vascular engorgement that can also result from the growing uterus.Tell your doctor about this so that you can be checked to be sure your cervix isn't shortening or funneling increasing the risk of premature delivery.That said, it is likely to be normal.Good luck.Lucky baby!
