is this my mucus?

this has been coming out of me since last week it would come out little or big and sometimes it would come out and have a blood streak, my doctor saw and wanna keep me coming in every week since i'm already high risk, i cramp everyday literally and i know the difference between cramps and braxton hicks and real contractions because this isn't my first baby, everything happening soon is so new to me idk if i should be worried or not, baby is fine, last week my cervix was measured at 4.9cm and now 3.2 this week and my doctor told me again to keep coming in every week until he makes a decision and idk what the decision is....im only 27 weeks
