with each of my pregnancies, before i found out I WAS pregnant, I was certain that I was NOT pregnant, due to the bad cramping...I thought I was really really PMSy. So, both times, it was a huge shock to find I was actually pregnant...even the second time, it didn't matter that I'd experienced it with my first, when I learnt I was pregnant it was still a scary feeling....your mind still says "danger" when you have pain during pregnancy - but it is so very normal. Pinching sounds like nerves being squished - very normal in pregnancy. Take care.
