29 weeks symptoms/feelings

I am 29 weeks and I feel 9 months pregnant. Today especially I felt my baby resting heavily on pubic bone area and pushing which made it difficult to walk. I also feel weird pains such as heavy stomacg and tightning and a shortness of breathe like baby is resting somewhere. Hapoy baby movement has increase a lot more cause I was tolf that's always a good sign. and lastly loose stool but no tummy ache ..I think my stomach muscles have losen causing this loose stool but not sure.
