is this my bloody show? 35+2

Hi, yesterday I lost some mucus with blood and was having irregular tightenings (which were braxton hicks). I went to hosp to be checked, I had an internal exam and my cervix is fully closed thankfully. My last son was born at 31 weeks so have history of pre-term labour. Does this mean I'm going to go into labour soon? Really hoping I can make it to at least 37 weeks!
