I need some mommies insight please!

Amanda
Mommies out there, I have a question. Half way through pregnancy have you ever experienced a lot of pressure in vaginal area to the point it's hard to pee? I feel as I have to literally push to urinate. They checked my urine and everything came back perfectly normal... I also do have sciatic nerve.(sciatica) also, I been completely off balance. My head will get shooting pain and I have loss of appetite. I have my doctor appointment for my ultrasound scan today so I'm going to bring all this up again. Just wanted other moms insight to help calm my nerves . Thank you!
