Is this normal?

Anna • married to the most wonderful husband in the world, a mom to a beautiful angel baby and my handsome rainbow baby boy grason j.Green!!!!💙💙💙 23 years old

So I am 35 weeks will be 36 weeks on Monday and I have noticed over the past 3 days that I have had a lot of pressure on my cervix when I’m walking or when Grason (baby) is moving and I’m having horrible back pain as well to the point I can’t breath or move, just plain can’t do nothing.... also I have lost big chunks of mucus plug but haven’t had bloody show or anything but they are pretty good size chunks!! Ftm by the way just a super big worrier!! Also my Braxton Hicks contractions are hurting in my back as well could it mean baby is coming early or am I just not handling pregnancy very well😂😂

^this is 35 weeks tonight right before posting
