Labor with SPD insight

I’ve been suffering with horrible spd since 24 weeks and I’m now currently 34.6 weeks along. I’m in constant pain and it makes me nervous for trying for a vbac this time around. I’m scared I’m either going to be in extreme pain or not know I’m going into labor because I’m already in so much daily pain 😅 has anyone given birth while getting daily spd pain? What was it like? I’m trying not to get pain meds too early this time around since that’s what slowed down my labor last time 🤦🏻‍♀️
