Vaginal Pressure and Braxton Hicks 19th week

M
I'm 41. Everything has gone smoothly so far. Yes, I've had fatigue and itchy skin and headaches and nausea earlier on ... constant peeing etc but nothing scary. This is my second pregnancy. My son is 18 yrs old. This morning I'm getting vaginal pressure much like I get when I have my period and I've been experiencing Braxton hicks for the last couple of weeks. I called my health care provider when that started. I'm scheduled to see her again in two days. I'm concerned about the pressure. Is anyone else having similar symptoms?
