It sounds like you may have a condition called "milk bleb" or a "milk blister" on your left breast. This can cause a white, jelly-like substance to appear in your milk. It is not necessarily mastitis, but it's always best to consult with a healthcare professional to confirm the diagnosis. To help relieve the milk bleb and ensure a smooth breastfeeding journey, you can try a few tips: 1. Apply a warm compress or take a warm shower before breastfeeding or pumping to help soften the milk duct. 2. Gently massage the affected area towards the nipple to help clear the blockage. 3. Nurse or pump frequently on the affected side to ensure proper milk flow. 4. Ensure proper latch and positioning while breastfeeding to prevent further issues. If the issue persists or you experience any pain or fever, it's important to seek advice from a lactation consultant or your healthcare provider. Remember, every breastfeeding journey is unique, and it's okay to seek support and guidance when needed. If you're looking for additional support or products to enhance your breastfeeding experience, you may consider using a breast milk enhancer like the one available at this link: [Breast Milk Enhancer](https://invl.io/cll7ha0).
