Cramp like contractions, extremely sore vagina

I am currently 38 weeks and 4 days pregnant with baby number 2. I've been having cramp like contractions since I woke up this morning. They aren't exactly 3-5 minutes apart but painful enough to make me stop what I'm doing and breathe when they occur. Also, since yesterday I've been feeling extreme pain in my vagina as if someone had kicked me repeatedly, it's also so bad that my husband had to help me get dressed because I couldn't lift my leg up. I never experienced this with my son. I experienced some pain earlier on in my pregnancy and my midwife explained it was from my pelvic bone widening since I am naturally smaller framed. However, with that being said this pain is far worse from what I was previously feeling.
