Slight pressure

Brittany • Mommy to a little girl & one on the way 💗

I am 16 weeks & 2 days. In the middle of the night last night I felt a slight pressure or heaviness in my vagina. The feeling made me feel like I constantly had to pee. The pressure is gone but still feel the urge to pee a lot. No cramping, no backache.. just the pressure . Should I be concerned or is this normal? I am carrying low, could the baby be laying low causing this?
