not too hard it knocked me a few feet what happened was my car slid off the road then another car slid of and hit mine pushing mine into me and it hit me left side. i was sore for a while and when i peed it sort of hurt a little bit in my abdomen because the muscle was sore and now my insides still feel weird kind of tingley sometime and sometime quick mild stabbing pains.could this by car accident related? or could it be something worse like pregnant i am on the pill but have heard horror stories of ppl getting pregnant on pill. Or could it just be something entirely unrelated like poor diet? i went to a doctor a week after my accident he didnt think an x ray was necessary nothing broken.
