Painful 4 months postpartum sex

So I'm currently 4 months postpartum and sex is still painful. Some of that is due to dryness since I'm breastfeeding but lube seems to be helping in that area. The pain that I'm experiencing though is a sharp burning pain and it's not where I was stitched up (I had a 2nd degree tear), it feels like it's actually somewhere deeper inside. Did anyone have this and if so did anything help? Wondering if it's time to call my OBGYN or if I should just wait it out a little longer 😖
