Pressure in pelvis, 25 weeks pregnant

Ladies, I am currently 25 weeks and some days with baby #4 and have had lots of uncomfortable cramping and BH the last week or two. Today in the shower I had a painful BH and then about 8-10 minutes later another and it’s painful but not something that stops me mid conversation so I know it’s nothing real. This is continuous over the last 2 hours now. I’m now having tons of very low pelvic pressure like she will fall out and it’s uncomfortable, and I’m feeling zaps in my cervix. If I touch my lowest part of my belly by my pelvic area it is hard like I can feel the baby. Could this mean she is dropping lower? I have bad SPD so pelvic bones are separated already. Also had extra white creamy discharge today each time I used the bathroom. I’m drinking water to see if it helps and I’m lying down too. Is this normal?
