Night feeds help

I’m 7 weeks pp. My little one used to be up at least once, sometimes twice a night for feeding. But the last few nights he’s been sleeping longer stretches and I’m worried it will affect my supply if I drop night feeds this early. Like last night it was 7 hrs between nursing. I set alarms on my phone to wake up and either try to nurse or pump but I sleep right through them 😕 I even would put my phone on the other side of the room so I’d have to get out of bed to turn it off but even then I just shut the alarm off and go back to sleep ( without remembering in the morning). Is this going to decrease my supply and ruin breastfeeding? When he cries I do wake but can’t seem to for the alarm clock. Any advice?
