Mucus plug??

Mom friends! This is my second baby and let me start by saying this pregnancy has been DIFFICULT. With my first I did have him early at 36 weeks but I was already admitted to the hospital for preeclampsia and my water just broke. Okay well now I am 32 weeks pregnant with my second and I’ve already gone into preterm labor twice now. Both times being able to stop it with minimal stay at the hospital.. I got up this morning and this is what I saw when I wiped.. the first picture is the first pee, the other 3 are my second pee of the day. Think it’s my mucus plug? At my last admission I was 1cm and a quarter dilated.
