second pregnancy, help!!

Taylor

so i’m 33 weeks and 5 days, i’ve been having a some complications for the last 6-7 weeks like losing some chunks of my mucous plug(no bloody show), contractions(that i had to go to the hospital for, found out i’m 1cm dilated as of 31 weeks pregnant), amniotic fluid leaking, extreme lower back pain these last couple days, etc. the last two nights i have been having super quick and sharp pains in my vagina (8-9/10 on a pain scale) and i don’t know what it is. is he engaged? am i dilating? this is my second pregnancy but i didn’t really go through something like this with my first.
