Is this normal

I’m 33 weeks and 4 days pregnant. I been dilating and effaced for weeks now, 3cm and 80% baby is -2 for engagement that last time I got checked. I feel off, sick to my stomach, not really wanting to eat. My stomach hurts blow my pants, I have pressure/feeling like I need to poop. Sharp pains inside my vagina that comes and goes. My lower back has a dull ache pain to it. I also feel shaky everywhere like my hands are shaking a lot. Is this normal? My husband isn’t home for a few more hours so I been trying to wait it out until he comes home as he has our vehicle with the car seats in it and I’m home alone with my 2 year old
