I'm having the same problem this past week! I think mine is bc I'm getting close to my due date & everything is starting to spread, lower, & prepare for birth! It hurts tho! Feels like somebody kicked me in the Vag. ):
Pressure can also be a uti. They're probably checking urine at all doc appts but you should definitely mention to doc. I had one with no other symptoms except pressure.
It's possible that your baby just dropped, meaning it's getting ready for when you go into labor. My baby boy sat really low in me and I always had extreme pressure. At times I felt like he was going to just crawl out of there but the doc just said it's because he was so low and there was nothing to worry about. If you start getting really bad pain and cramping call your doctor tomorrow. If it's nothing then at least you will have piece of mind:)
