feeling a lot of pressure in lower stomach/vagina anyone else?

Kate
Im 22 weeks and I have started feeling a lot of pressure in my lower stomach and vagina area for the past 4 days my doctors office (nurse) said it was just a discomfort that came along with being pregnant and not a concern but I'm still concerned idk if I should call back and get the doctor to answer that question or just let it go. Anyone else feeling any pressure ?
