Itchy/pain in csection scar in second pregnancy.

I had an emergency section last July. My baby was 24 weeks and passed away 3 hours after birth. I'm now 31 weeks pregnant again with a healthy baby thankfully but due to the short amount of time between births I'm going for a planned section this time at 39 weeks. I am allowed to try for a VBAC if I wish but I don't want to - intuition tells me it isnt safe.

My question is - ever since I reached 3rd trimester my previous scar has got super itchy and sometimes painful. Do you think this is a bad sign that my scar could rupture if I went for VBAC.

Noone has ever asked me about my scar in any appointments. Do you think I should ask someone to check it? They cut into the same scar, right?
