Hard breasts towards end of pregnancy

Hi I’m a 2nd time mom here! I’m only at 35 weeks right now but my breasts are so hard. Reminds me of my breasts at around 3 days postpartum when the milk starts to buildup to become engorged. Any idea what I should do? I’m afraid of trying to hand express because I’m at high risk of pre-term labour in the next week or 2. 😅
