Women who have already given birth...?

i dont know how to describe it but when im getting dressed or i lift my leg up or i strain my legs or something, my vagina hurts. it feels like its inside not necessarily my vagina... can you feel when your dilating or effacing? i have been really nauseous for the past few days, and last night about an hour before bed i started getting contractions, but they were still irregular and kind of a mixture between braxton hicks and regular contractions. is labor on its way? please tell me yes!!!
