To start my baby is posterior,

My due date was 3 days ago and this is baby #2.

I have been feeling cramps for weeks,but last night I had the WORST pain in my abdomen and I swear I was feeling contractions in my back.

Does that mean labor is very close? I'm still in pain this morning,my body is soooo sore. the pressure I feel in my vagina is ridiculous.

I was induced with my first and everything was smooth and honestly painless.

This time I wanna do it natural at a birthing center but am scared since he is sunny side up
