This is going ot sound ridiculous, and I am probably just paranoid...but how difficult is it to get air in the

uterus? I usually queefe during rear entry style (TMI, Sorry) but we are trying to conceive, so I have been using pre-seed lubricant. It came in these little plastic pre-filled applicators and half the applicator was filled with air and in order to push the liquid in you had to squeeze the end with air. I find it difficult to apply without getting air bubbles inside of me. Could this have increased the chances of getting air in my uterus during the we had afterwards? I felt some twinges of pain, but I am also ovulating and it might have been that...I am paranoid. Please advise.
