I'm only 9+5 weeks and last night was my sons birthday. It lasted 2 hours and I was on my feet most of the time, but say whenever I had the chance. Well by the end of the night, I started experiencing slight pain where my scar is and by the time I got home, I had pulsating stabbing pain and bad pelvic pressure, mainly when I stood up and walked. Is this normal or should I be concerned and call my dr. This is my 2nd pregnancy. This time I have an anterior placenta and am also taking medication for a UTI for the last 3 days. I didn't have any symptoms for it, the Irvine test at ob office found it.
